Breech, posterior, transverse lie: What position is my baby in?

Layan Alrahmani, M.D.

Fetal presentation, or how your baby is situated in your womb at birth, is determined by the body part that's positioned to come out first, and it can affect the way you deliver. At the time of delivery, 97 percent of babies are head-down (cephalic presentation). But there are several other possibilities, including feet or bottom first (breech) as well as sideways (transverse lie) and diagonal (oblique lie).

Fetal presentation and position

During the last trimester of your pregnancy, your provider will check your baby's presentation by feeling your belly to locate the head, bottom, and back. If it's unclear, your provider may do an ultrasound or an internal exam to feel what part of the baby is in your pelvis.

Fetal position refers to whether the baby is facing your spine (anterior position) or facing your belly (posterior position). Fetal position can change often: Your baby may be face up at the beginning of labor and face down at delivery.

Here are the many possibilities for fetal presentation and position in the womb.

Medical illustrations by Jonathan Dimes

Head down, facing down (anterior position)

A baby who is head down and facing your spine is in the anterior position. This is the most common fetal presentation and the easiest position for a vaginal delivery.

This position is also known as "occiput anterior" because the back of your baby's skull (occipital bone) is in the front (anterior) of your pelvis.

Head down, facing up (posterior position)

In the posterior position , your baby is head down and facing your belly. You may also hear it called "sunny-side up" because babies who stay in this position are born facing up. But many babies who are facing up during labor rotate to the easier face down (anterior) position before birth.

Posterior position is formally known as "occiput posterior" because the back of your baby's skull (occipital bone) is in the back (posterior) of your pelvis.

Frank breech

In the frank breech presentation, both the baby's legs are extended so that the feet are up near the face. This is the most common type of breech presentation. Breech babies are difficult to deliver vaginally, so most arrive by c-section .

Some providers will attempt to turn your baby manually to the head down position by applying pressure to your belly. This is called an external cephalic version , and it has a 58 percent success rate for turning breech babies. For more information, see our article on breech birth .

Complete breech

A complete breech is when your baby is bottom down with hips and knees bent in a tuck or cross-legged position. If your baby is in a complete breech, you may feel kicking in your lower abdomen.

Incomplete breech

In an incomplete breech, one of the baby's knees is bent so that the foot is tucked next to the bottom with the other leg extended, positioning that foot closer to the face.

Single footling breech

In the single footling breech presentation, one of the baby's feet is pointed toward your cervix.

Double footling breech

In the double footling breech presentation, both of the baby's feet are pointed toward your cervix.

Transverse lie

In a transverse lie, the baby is lying horizontally in your uterus and may be facing up toward your head or down toward your feet. Babies settle this way less than 1 percent of the time, but it happens more commonly if you're carrying multiples or deliver before your due date.

If your baby stays in a transverse lie until the end of your pregnancy, it can be dangerous for delivery. Your provider will likely schedule a c-section or attempt an external cephalic version , which is highly successful for turning babies in this position.

Oblique lie

In rare cases, your baby may lie diagonally in your uterus, with his rump facing the side of your body at an angle.

Like the transverse lie, this position is more common earlier in pregnancy, and it's likely your provider will intervene if your baby is still in the oblique lie at the end of your third trimester.

Fetal Positions for Labor and Birth

Knowing your baby's position can you help ease pain and speed up labor

In the last weeks of pregnancy , determining your baby's position can help you manage pain and discomfort. Knowing your baby's position during early labor can help you adjust your own position during labor and possibly even speed up the process.

Right or Left Occiput Anterior

Illustration by JR Bee, Verywell 

Looking at where the baby's head is in the birth canal helps determine the fetal position.The front of a baby's head is referred to as the anterior portion and the back is the posterior portion. There are two different positions called occiput anterior (OA) positions that may occur.

The left occiput anterior (LOA) position is the most common in labor. In this position, the baby's head is slightly off-center in the pelvis with the back of the head toward the mother's left thigh.

The right occiput anterior (ROA) presentation is also common in labor. In this position, the back of the baby is slightly off-center in the pelvis with the back of the head toward the mother's right thigh.

In general, OA positions do not lead to problems or additional pain during labor or birth.  

Right or Left Occiput Transverse

Illustration by JR Bee, Verywell  

When facing out toward the mother's right thigh, the baby is said to be left occiput transverse (LOT). This position is halfway between a posterior and anterior position. If the baby was previously in a posterior position (in either direction), the LOT position indicates positive movement toward an anterior position.

When the baby is facing outward toward the mother's left thigh, the baby is said to be right occiput transverse (ROT). Like the previous presentation, ROT is halfway between a posterior and anterior position. If the baby was previously in a posterior position, ROT is a sign the baby is making a positive move toward an anterior position.

When a baby is in the left occiput transverse position (LOT) or right occiput transverse (ROT) position during labor, it may lead to more pain and a slower progression.

Tips to Reduce Discomfort

There are several labor positions a mother can try to alleviate pain and encourage the baby to continue rotating toward an anterior position, including:

  • Pelvic tilts
  • Standing and swaying

A doula , labor nurse, midwife , or doctor may have other suggestions for positions.

Right or Left Occiput Posterior

When facing forward, the baby is in the occiput posterior position. If the baby is facing forward and slightly to the left (looking toward the mother's right thigh) it is in the left occiput posterior (LOP) position. This presentation can lead to more back pain (sometimes referred to as " back labor ") and slow progression of labor.

In the right occiput posterior position (ROP), the baby is facing forward and slightly to the right (looking toward the mother's left thigh). This presentation may slow labor and cause more pain.

To help prevent or decrease pain during labor and encourage the baby to move into a better position for delivery, mothers can try a variety of positions, including:

  • Hands and knees
  • Pelvic rocking

Mothers may try other comfort measures, including:

  • Bathtub or shower (water)
  • Counter pressure
  • Movement (swaying, dancing, sitting on a birth ball )
  • Rice socks (heat packs)

How a Doctor Determines Baby's Position

Leopold's maneuvers are a series of hands-on examinations your doctor or midwife will use to help determine your baby's position. During the third trimester , the assessment will be done at most of your prenatal visits.   Knowing the baby's position before labor begins can help you prepare for labor and delivery.

Once labor begins, a nurse, doctor, or midwife will be able to get a more accurate sense of your baby's position by performing a vaginal exam. When your cervix is dilated enough, the practitioner will insert their fingers into the vagina and feel for the suture lines of the baby's skull as it moves down in the birth canal.   It's important to ensure the baby is head down and moving in the right direction.

Labor and delivery may be more complicated if the baby is not in a head-down position, such as in the case of a breech presentation.

How You Can Determine Baby's Position

While exams by health practitioners are an important part of your care, from the prenatal period through labor and delivery, often the best person to assess a baby's position in the pelvis is you. Mothers should pay close attention to how the baby moves and where different movements are felt.

A technique called belly mapping can help mothers ask questions of themselves to assess their baby's movement and get a sense of the position they are in as labor approaches.

For example, the position of your baby's legs can be determined by asking questions about the location and strength of the kicking you feel. The spots where you feel the strongest kicks are most likely where your baby's feet are.

Other landmarks you can feel for include a large, flat plane, which is most likely your baby's back. Sometimes you can feel the baby arching his or her back.

At the top or bottom of the flat plane, you may feel either a hard, round shape (most likely your baby's head) or a soft curve (most likely to be your baby's bottom).

Fetal Presentation, Position, and Lie (Including Breech Presentation)

  • Variations in Fetal Position and Presentation |

During pregnancy, the fetus can be positioned in many different ways inside the mother's uterus. The fetus may be head up or down or facing the mother's back or front. At first, the fetus can move around easily or shift position as the mother moves. Toward the end of the pregnancy the fetus is larger, has less room to move, and stays in one position. How the fetus is positioned has an important effect on delivery and, for certain positions, a cesarean delivery is necessary. There are medical terms that describe precisely how the fetus is positioned, and identifying the fetal position helps doctors to anticipate potential difficulties during labor and delivery.

Presentation refers to the part of the fetus’s body that leads the way out through the birth canal (called the presenting part). Usually, the head leads the way, but sometimes the buttocks (breech presentation), shoulder, or face leads the way.

Position refers to whether the fetus is facing backward (occiput anterior) or forward (occiput posterior). The occiput is a bone at the back of the baby's head. Therefore, facing backward is called occiput anterior (facing the mother’s back and facing down when the mother lies on her back). Facing forward is called occiput posterior (facing toward the mother's pubic bone and facing up when the mother lies on her back).

Lie refers to the angle of the fetus in relation to the mother and the uterus. Up-and-down (with the baby's spine parallel to mother's spine, called longitudinal) is normal, but sometimes the lie is sideways (transverse) or at an angle (oblique).

For these aspects of fetal positioning, the combination that is the most common, safest, and easiest for the mother to deliver is the following:

Head first (called vertex or cephalic presentation)

Facing backward (occiput anterior position)

Spine parallel to mother's spine (longitudinal lie)

Neck bent forward with chin tucked

Arms folded across the chest

If the fetus is in a different position, lie, or presentation, labor may be more difficult, and a normal vaginal delivery may not be possible.

Variations in fetal presentation, position, or lie may occur when

The fetus is too large for the mother's pelvis (fetopelvic disproportion).

The uterus is abnormally shaped or contains growths such as fibroids .

The fetus has a birth defect .

There is more than one fetus (multiple gestation).

Position and Presentation of the Fetus

Variations in fetal position and presentation.

Some variations in position and presentation that make delivery difficult occur frequently.

Occiput posterior position

In occiput posterior position (sometimes called sunny-side up), the fetus is head first (vertex presentation) but is facing forward (toward the mother's pubic bone—that is, facing up when the mother lies on her back). This is a very common position that is not abnormal, but it makes delivery more difficult than when the fetus is in the occiput anterior position (facing toward the mother's spine—that is facing down when the mother lies on her back).

When a fetus faces up, the neck is often straightened rather than bent,which requires more room for the head to pass through the birth canal. Delivery assisted by a vacuum device or forceps or cesarean delivery may be necessary.

Breech presentation

In breech presentation, the baby's buttocks or sometimes the feet are positioned to deliver first (before the head).

When delivered vaginally, babies that present buttocks first are more at risk of injury or even death than those that present head first.

The reason for the risks to babies in breech presentation is that the baby's hips and buttocks are not as wide as the head. Therefore, when the hips and buttocks pass through the cervix first, the passageway may not be wide enough for the head to pass through. In addition, when the head follows the buttocks, the neck may be bent slightly backwards. The neck being bent backward increases the width required for delivery as compared to when the head is angled forward with the chin tucked, which is the position that is easiest for delivery. Thus, the baby’s body may be delivered and then the head may get caught and not be able to pass through the birth canal. When the baby’s head is caught, this puts pressure on the umbilical cord in the birth canal, so that very little oxygen can reach the baby. Brain damage due to lack of oxygen is more common among breech babies than among those presenting head first.

In a first delivery, these problems may occur more frequently because a woman’s tissues have not been stretched by previous deliveries. Because of risk of injury or even death to the baby, cesarean delivery is preferred when the fetus is in breech presentation, unless the doctor is very experienced with and skilled at delivering breech babies or there is not an adequate facility or equipment to safely perform a cesarean delivery.

Breech presentation is more likely to occur in the following circumstances:

Labor starts too soon (preterm labor).

The uterus is abnormally shaped or contains abnormal growths such as fibroids .

Other presentations

In face presentation, the baby's neck arches back so that the face presents first rather than the top of the head.

In brow presentation, the neck is moderately arched so that the brow presents first.

Usually, fetuses do not stay in a face or brow presentation. These presentations often change to a vertex (top of the head) presentation before or during labor. If they do not, a cesarean delivery is usually recommended.

In transverse lie, the fetus lies horizontally across the birth canal and presents shoulder first. A cesarean delivery is done, unless the fetus is the second in a set of twins. In such a case, the fetus may be turned to be delivered through the vagina.

Delivery, face and brow presentation.

Last Update: January 9, 2023 .

  • Continuing Education Activity

Face and brow presentation is a malpresentation during labor when the presenting part is either the face or, in the case of brow presentation, it is the area between the orbital ridge and the anterior fontanelle. This activity reviews the evaluation and management of these two presentations and explains the role of the interprofessional team in managing delivery safely for both the mother and the baby.

  • Describe the mechanism of labor in the face and brow presentation.
  • Summarize potential maternal and fetal complications during the face and brow presentations.
  • Review different management approaches for the face and brow presentation.
  • Outline some interprofessional strategies that will improve patient outcomes in delivery cases with face and brow presentation issues.
  • Introduction

The term presentation describes the leading part of the fetus or the anatomical structure closest to the maternal pelvic inlet during labor. The presentation can roughly be divided into the following classifications: cephalic, breech, shoulder, and compound. Cephalic presentation is the most common and can be further subclassified as vertex, sinciput, brow, face, and chin. The most common presentation in term labor is the vertex, where the fetal neck is flexed to the chin, minimizing the head circumference.

Face presentation – an abnormal form of cephalic presentation where the presenting part is mentum. This typically occurs because of hyperextension of the neck and the occiput touching the fetal back. Incidence of face presentation is rare, accounting for approximately 1 in 600 of all presentations. [1] [2] [3]

In brow presentation, the neck is not extended as much as in face presentation, and the leading part is the area between the anterior fontanelle and the orbital ridges. Brow presentation is considered the rarest of all malpresentation with a prevalence of 1 in 500 to 1 in 4000 deliveries. [3]

Both face and brow presentations occur due to extension of the fetal neck instead of flexion; therefore, conditions that would lead to hyperextension or prevent flexion of the fetal neck can all contribute to face or brow presentation. These risk factors may be related to either the mother or the fetus. Maternal risk factors are preterm delivery, contracted maternal pelvis, platypelloid pelvis, multiparity, previous cesarean section, black race. Fetal risk factors include anencephaly, multiple loops of cord around the neck, masses of the neck, macrosomia, polyhydramnios. [2] [4] [5]

These malpresentations are usually diagnosed during the second stage of labor when performing a digital examination. It is possible to palpate orbital ridges, nose, malar eminences, mentum, mouth, gums, and chin in face presentation. Based on the position of the chin, face presentation can be further divided into mentum anterior, posterior, or transverse. In brow presentation, anterior fontanelle and face can be palpated except for the mouth and the chin. Brow presentation can then be further described based on the position of the anterior fontanelle as frontal anterior, posterior, or transverse.

Diagnosing the exact presentation can be challenging, and face presentation may be misdiagnosed as frank breech. To avoid any confusion, a bedside ultrasound scan can be performed. [6]  The ultrasound imaging can show a reduced angle between the occiput and the spine or, the chin is separated from the chest. However, ultrasound does not provide much predicting value in the outcome of the labor. [7]

  • Anatomy and Physiology

Before discussing the mechanism of labor in the face or brow presentation, it is crucial to highlight some anatomical landmarks and their measurements. 

Planes and Diameters of the Pelvis

The three most important planes in the female pelvis are the pelvic inlet, mid pelvis, and pelvic outlet. 

Four diameters can describe the pelvic inlet: anteroposterior, transverse, and two obliques. Furthermore, based on the different landmarks on the pelvic inlet, there are three different anteroposterior diameters, named conjugates: true conjugate, obstetrical conjugate, and diagonal conjugate. Only the latter can be measured directly during the obstetric examination. The shortest of these three diameters is obstetrical conjugate, which measures approximately 10.5 cm and is a distance between the sacral promontory and 1 cm below the upper border of the symphysis pubis. This measurement is clinically significant as the fetal head must pass through this diameter during the engagement phase. The transverse diameter measures about 13.5cm and is the widest distance between the innominate line on both sides. 

The shortest distance in the mid pelvis is the interspinous diameter and usually is only about 10 cm. 

Fetal Skull Diameters

There are six distinguished longitudinal fetal skull diameters:

  • Suboccipito-bregmatic: from the center of anterior fontanelle (bregma) to the occipital protuberance, measuring 9.5 cm. This is the presenting diameter in vertex presentation. 
  • Suboccipito-frontal: from the anterior part of bregma to the occipital protuberance, measuring 10 cm 
  • Occipito-frontal: from the root of the nose to the most prominent part of the occiput, measuring 11.5cm
  • Submento-bregmatic: from the center of the bregma to the angle of the mandible, measuring 9.5 cm. This is the presenting diameter in face presentation where the neck is hyperextended. 
  • Submento-vertical: from the midpoint between fontanelles and the angle of the mandible, measuring 11.5cm 
  • Occipito-mental: from the midpoint between fontanelles and the tip of the chin, measuring 13.5 cm. It is the presenting diameter in brow presentation. 

Cardinal Movements of Normal Labor

  • Neck flexion
  • Internal rotation
  • Extension (delivers head)
  • External rotation (Restitution)
  • Expulsion (delivery of anterior and posterior shoulders)

Some of the key movements are not possible in the face or brow presentations.  

Based on the information provided above, it is obvious that labor will be arrested in brow presentation unless it spontaneously changes to face or vertex, as the occipito-mental diameter of the fetal head is significantly wider than the smallest diameter of the female pelvis. Face presentation can, however, be delivered vaginally, and further mechanisms of face delivery will be explained in later sections.

  • Indications

As mentioned previously, spontaneous vaginal delivery can be successful in face presentation. However, the main indication for vaginal delivery in such circumstances would be a maternal choice. It is crucial to have a thorough conversation with a mother, explaining the risks and benefits of vaginal delivery with face presentation and a cesarean section. Informed consent and creating a rapport with the mother is an essential aspect of safe and successful labor.

  • Contraindications

Vaginal delivery of face presentation is contraindicated if the mentum is lying posteriorly or is in a transverse position. In such a scenario, the fetal brow is pressing against the maternal symphysis pubis, and the short fetal neck, which is already maximally extended, cannot span the surface of the maternal sacrum. In this position, the diameter of the head is larger than the maternal pelvis, and it cannot descend through the birth canal. Therefore the cesarean section is recommended as the safest mode of delivery for mentum posterior face presentations. 

Attempts to manually convert face presentation to vertex, manual or forceps rotation of the persistent posterior chin to anterior are contraindicated as they can be dangerous.

Persistent brow presentation itself is a contraindication for vaginal delivery unless the fetus is significantly small or the maternal pelvis is large.

Continuous electronic fetal heart rate monitoring is recommended for face and brow presentations, as heart rate abnormalities are common in these scenarios. One study found that only 14% of the cases with face presentation had no abnormal traces on the cardiotocograph. [8] It is advised to use external transducer devices to prevent damage to the eyes. When internal monitoring is inevitable, it is suggested to place monitoring devices on bony parts carefully. 

People who are usually involved in the delivery of face/ brow presentation are:

  • Experienced midwife, preferably looking after laboring woman 1:1
  • Senior obstetrician 
  • Neonatal team - in case of need for resuscitation 
  • Anesthetic team - to provide necessary pain control (e.g., epidural)
  • Theatre team  - in case of failure to progress and an emergency cesarean section will be required.
  • Preparation

No specific preparation is required for face or brow presentation. However, it is essential to discuss the labor options with the mother and birthing partner and inform members of the neonatal, anesthetic, and theatre co-ordinating teams.

  • Technique or Treatment

Mechanism of Labor in Face Presentation

During contractions, the pressure exerted by the fundus of the uterus on the fetus and pressure of amniotic fluid initiate descent. During this descent, the fetal neck extends instead of flexing. The internal rotation determines the outcome of delivery, if the fetal chin rotates posteriorly, vaginal delivery would not be possible, and cesarean section is permitted. The approach towards mentum-posterior delivery should be individualized, as the cases are rare. Expectant management is acceptable in multiparous women with small fetuses, as a spontaneous mentum-anterior rotation can occur. However, there should be a low threshold for cesarean section in primigravida women or women with large fetuses.

When the fetal chin is rotated towards maternal symphysis pubis as described as mentum-anterior; in these cases further descend through the vaginal canal continues with approximately 73% cases deliver spontaneously. [9] Fetal mentum presses on the maternal symphysis pubis, and the head is delivered by flexion. The occiput is pointing towards the maternal back, and external rotation happens. Shoulders are delivered in the same manner as in vertex delivery.

Mechanism of Labor in Brow Presentation

As this presentation is considered unstable, it is usually converted into a face or an occiput presentation. Due to the cephalic diameter being wider than the maternal pelvis, the fetal head cannot engage; thus, brow delivery cannot take place. Unless the fetus is small or the pelvis is very wide, the prognosis for vaginal delivery is poor. With persistent brow presentation, a cesarean section is required for safe delivery.

  • Complications

As the cesarean section is becoming a more accessible mode of delivery in malpresentations, the incidence of maternal and fetal morbidity and mortality during face presentation has dropped significantly. [10]

However, there are still some complications associated with the nature of labor in face presentation. Due to the fetal head position, it is more challenging for the head to engage in the birth canal and descend, resulting in prolonged labor.

Prolonged labor itself can provoke foetal distress and arrhythmias. If the labor arrests or signs of fetal distress appear on CTG, the recommended next step in management is an emergency cesarean section, which in itself carries a myriad of operative and post-operative complications.

Finally, due to the nature of the fetal position and prolonged duration of labor in face presentation, neonates develop significant edema of the skull and face. Swelling of the fetal airway may also be present, resulting in respiratory distress after birth and possible intubation.

  • Clinical Significance

During vertex presentation, the fetal head flexes, bringing the chin to the chest, forming the smallest possible fetal head diameter, measuring approximately 9.5cm. With face and brow presentation, the neck hyperextends, resulting in greater cephalic diameters. As a result, the fetal head will engage later, and labor will progress more slowly. Failure to progress in labor is also more common in both presentations compared to vertex presentation.

Furthermore, when the fetal chin is in a posterior position, this prevents further flexion of the fetal neck, as browns are pressing on the symphysis pubis. As a result, descend through the birth canal is impossible. Such presentation is considered undeliverable vaginally and requires an emergency cesarean section.

Manual attempts to change face presentation to vertex, manual or forceps rotation to mentum anterior are considered dangerous and are discouraged.

  • Enhancing Healthcare Team Outcomes

A multidisciplinary team of healthcare experts supports the woman and her child during labor and the perinatal period. For a face or brow presentation to be appropriately diagnosed, an experienced midwife and obstetrician must be involved in the vaginal examination and labor monitoring. As fetal anomalies, such as anencephaly or goiter, can contribute to face presentation, sonographers experienced in antenatal scanning should also be involved in the care. It is advised to inform the anesthetic and neonatal teams in advance of the possible need for emergency cesarean section and resuscitation of the neonate. [11] [12]

What to know about baby’s position at birth

Ideal birth position (occiput anterior)

Having a baby is an exciting time, but it’s common to have some worries about labor and delivery. One thing that often causes mums-to-be concern is what position their baby will be in when the time comes for them to be born.

For a vaginal delivery, the baby must descend through the birth canal, passing through your pelvis to reach the vaginal opening. The position of the baby - or presentation of the fetus as it is also known - affects how quickly and easily the baby can be born. Some positions allow the baby to tuck their chin, and re-position and rotate their head to make their journey easier.

Here’s a guide to help you understand the language used to describe the position of babies and some tips for helping them into the ideal position for birth.

Position of the baby before birth

During pregnancy your baby has room to move about in your uterus or womb - twisting, turning, rolling, stretching and getting in some kicks. As your pregnancy progresses and they grow bigger there’s less room for them to move, but your baby should still move regularly until they are born, even during labor.

Sometime between 32 and 38 weeks of pregnancy, but usually around week 36, babies tend to move into a head down position. This allows their head to come out of your vagina first when they are born. Only about 3 to 4 percent of babies do not move into a head-first or cephalic presentation before birth.

What’s the ideal position of a baby for birth?

Occiput anterior is the ideal presentation for your baby to be in for a vaginal delivery.

Occiput anterior is a type of head-first or cephalic presentation for delivery of a baby. About 95 to 97 percent of babies position themselves in a cephalic presentation for delivery, often with the crown or top of their head - which is also known as the vertex - entering the birth canal first.

Usually when a baby is being born in a vertex presentation the back of the baby’s head, which is called the occiput, is towards the front or anterior of your pelvis and their back is towards your belly. Their chin is also typically in a flexed position, tucked into their chest.

Occiput anterior is the best and safest position for a baby to be born by a vaginal birth. It allows the smallest diameter of a baby’s head to descend into the birth canal first, making it easier for the baby to fit through your pelvis.

What other positions are babies born in?

Sometimes babies don’t position themselves in the ideal position for birth. These other positions are called abnormal positions. Listed below are the abnormal positions or presentations that some babies are born in.

Occiput posterior or back-to-back presentation

Occiput posterior position or back-to-back presentation occurs when the occiput - back of a baby’s head - is positioned towards your tailbone or back during delivery. Sometimes this presentation is also called “sunny side up” because babies born in this position enter the world facing up. About 5 percent of babies are delivered in the occiput posterior position.

Babies presenting in the occiput posterior position find it harder to make their way through the birth canal, which can lead to a longer labor. This presentation is three times more likely to end in a cesarean section (c-section) compared with babies presenting in the ideal, occiput anterior presentation.

Breech presentation

A breech presentation occurs when your baby’s buttock, feet or both are set to come out first at birth. About 3 to 4 percent of full-term babies are born in a breech position.

There are three types of breech presentation including:

  • Frank breech. Frank breech is the most common breech presentation, occurring in 50 to 70 percent of breech births. Babies in the Frank breech position have their hips flexed and their knees extended so that their legs are folded flat against their head. Their bottom is closest to the birth canal.
  • Footling or incomplete breech. Footling or incomplete breeches occur in 10 to 30 percent of breech births. An incomplete breech presentation is where just one of the baby’s knees is bent up. Their other foot and bottom are closest to the birth canal. In a footling breech presentation, one or both feet may be delivered first.
  • Complete breech. A complete breech presentation is less common, occurring in 5 to 10 percent of breech births. Babies in a complete breech position have both knees bent and their feet and bottom are closest to the birth canal.

A breech delivery can result in the baby’s head or shoulders becoming stuck because opening to the uterus (cervix) may not be stretched enough by the baby’s body to allow the head and shoulders to pass through. Umbilical cord prolapse can also occur. This is when the cord slips into the vagina before the baby is delivered. If the cord is pinched then the flow of blood and oxygen to the baby can be reduced.

If an exam reveals your baby is sitting in a breech position and you’re past 36 weeks of pregnancy then external cephalic version (ECV) might be attempted to improve your chances of having a vaginal birth. ECV is performed by a qualified healthcare professional and it involves them pressing their hands on the outside of your belly to try and turn the baby.

Most babies found to be in a breech position are delivered by c-section because studies indicate that a vaginal delivery is about three times more likely to cause serious harm to the baby.

Brow and face presentations

Babies can also arrive brow- or face-first. A brow presentation results in the widest part of your baby’s head trying to fit through your pelvis first. This is a rare presentation, affecting about 1 in every 500 to 1400 births.

Instead of flexing and tucking their chin, babies presenting brow-first slightly extend their head and neck in the same way they would if they were looking up.

If your baby stays in a brow presentation it’s highly unlikely that they will be able to make their way through your pelvis. If your cervix is fully dilated then your doctor may be able to use their hand or ventouse - a vacuum cup - to move your baby’s head into a flexed position. If there are signs that your baby is becoming distressed or labor isn’t progressing then a c-section may be recommended.

More than half of the babies presenting brow-first, however, flex their head during early labor and move into a better position that allows labor to progress. Although, some babies tip their head back further and present face-first.

A face presentation is another rare position for a baby to be born in, occurring in only 1 in every 600 to 800 births.

Almost three quarters of babies presenting face-first can be delivered vaginally, especially if the baby’s chin is near your pubic bone, although labor may be prolonged.

Some baby’s presenting face-first may need to be delivered by c-section, particularly if their chin is near your tailbone, your labor is not progressing or your baby’s heart rate is causing concern.

Shoulder presentation

If your baby is lying sideways across your uterus - in a transverse lie - their shoulder can present first. Shoulder presentation occurs in less than 1 percent of deliveries. Virtually all babies in a shoulder presentation will need to be delivered by c-section. If labor begins while the baby is in this position then the shoulder will become stuck in the pelvis and the labor will not progress.

What factors can influence the position of my baby?

A number of factors can influence the position of your baby during labor and delivery, including:

  • If you have been pregnant before
  • The size and shape of your pelvis
  • Having an abnormally shaped uterus
  • Having growths in your uterus, such as fibroids
  • Having placenta previa - the placenta covers some or all of the cervix
  • A premature birth
  • Having twins or multiple babies
  • Having too much (polyhydramnios) or too little (oligohydramnios) amniotic fluid
  • Abnormalities that prevent the baby tucking their chin to their chest

How do I tell what position my baby is in?

Your midwife or your obstetrician-gynecologist (OB-GYN) should be able to tell you the position of your baby by feeling your belly, using an ultrasound scan or conducting a pelvic exam.

You might also be able to tell the position of the baby from their movements.

If your baby is in a back-to-back position your belly may feel more squishy and their kicks are likely to be felt or seen around the middle of your belly. You may also notice that instead of your belly poking out there is a dip around your belly button.

If your baby is in the ideal occiput anterior presentation you’re likely to feel the firm, rounded surface of your baby’s back on one side of your belly and feel kicks up under your ribs.

How do I get my baby into the best position for birth?

Here are some tips to try to encourage your baby to engage in the ideal position for birth:

  • Remain upright, but lean forward to create more space in your pelvis for your baby to turn.
  • Sit with your back as straight as possible and your knees lower than your hips. Placing a cushion under your bottom and one behind your back may make this position more comfortable. Avoid sitting with your knees higher than your pelvis.
  • When you read a book, sit on a dining room chair and rest your elbows on the table. Lean forward slightly with your knees apart. Avoid crossing your knees.
  • If pelvic girdle pain is not an issue, try sitting facing backwards with your arms resting on the back of a chair.
  • Watch TV kneeling on the floor leaning over a big bean bag.
  • Go for a swim.
  • Sit on a birth ball or swiss ball - they can be used both before and during labor.
  • Lie down on your side rather than your back. Place a pillow between your knees for comfort.
  • Try moving about on all fours. Try wiggling your hips or arching your back before straightening your spine again.
  • During Braxton Hicks (practice contractions), use a forward leaning posture
  • During contractions, stay on your feet, lean forwards and rock your hips from side to side and up and down to get your bottom wiggling as you walk

Remember to attend your antenatal appointments and contact your midwife or OB-GYN if you have any questions or concerns about the position of your baby.

INTRODUCTION

PATHOGENESIS AND RISK FACTORS

● The fetus does not fully occupy the pelvis, thus allowing a fetal extremity room to prolapse. Predisposing factors include early gestational age, multiple gestation, polyhydramnios, or a large maternal pelvis relative to fetal size [ 2,3 ].

● Membrane rupture occurs when the presenting part is still high, which allows flow of amniotic fluid to carry a fetal extremity, umbilical cord, or both toward the birth canal.

Delivery presentations

Delivery presentation describes the way the baby is positioned to come down the birth canal for delivery.

Your baby must pass through your pelvic bones to reach the vaginal opening. The ease at which this passage will take place depends on how your baby is positioned during delivery. The best position for the baby to be in to pass through the pelvis is with the head down and the body facing towards the mother's back. This position is called occiput anterior (OA).

In breech position, the baby's bottom is facing down instead of the head. Your health care provider will most often detect this in an office visit before your labor begins. Most babies will be in the head-down position by about 34 weeks.

Part of your prenatal care after 34 weeks will involve making sure your baby is in the head-down position.

If your baby is breech, it is not safe to deliver vaginally. If your baby is not in a head-down position after your 36th week, your provider can explain your choices and their risks to help you decide what steps to take next.

Occiput Posterior (OP)

In occiput posterior position, your baby's head is down, but it is facing the mother's front instead of her back.

It is safe to deliver a baby facing this way. But it is harder for the baby to get through the pelvis. If a baby is in this position, sometimes it will rotate around during labor so that the head stays down and the body faces the mother's back (OA position).

The mother can walk, rock, and try different delivery positions during labor to help encourage the baby to turn. If the baby does not turn, labor can take longer. Sometimes, the provider may use forceps or a vacuum device to help get the baby out. If the baby stays in the OP position during labor, you have a higher risk of needing to deliver your baby by cesarean delivery (C-section).

Transverse Position

A baby in the transverse position is sideways. Often, the shoulders or back are over the mother's cervix. This is also called the shoulder, or oblique, position.

The risk for having a baby in the transverse position increases if you:

  • Go into labor early
  • Have given birth 3 or more times
  • Have placenta previa

Unless your baby can be turned into head-down position, a vaginal birth will be too risky for you and your baby. A doctor will deliver your baby by cesarean birth ( C-section ).

Less Common Presentations

With the brow-first position, the baby's head extends backward (like looking up), and the forehead leads the way. This position may be more common if this is not your first pregnancy.

  • Your provider rarely detects this position before labor. An ultrasound may be able to confirm a brow presentation.
  • More likely, your provider will detect this position while you are in labor during an internal exam.

With face-first position, the baby's head is extended backwards even more than with brow first position.

  • Most of the time, the force of contractions causes the baby to be in face-first position.
  • It is also detected when labor does not progress.

In some of these presentations, a vaginal birth is possible, but labor will generally take longer. After delivery, the baby's face or brow will be swollen and may appear bruised. These changes will go away over the next few days.

Stages of labor and birth: Baby, it's time!

Labor is a natural process. Here's what to expect during the three stages of labor and birth — and what you can do to promote comfort.

Labor is a unique experience. Sometimes it's over in a matter of hours. In other cases, labor tests a mother's physical and emotional stamina.

You won't know how labor and childbirth will unfold until it happens. However, you can prepare by understanding the typical sequence of events.

Stage 1: Early labor and active labor

Cervical effacement and dilation

Cervical effacement and dilation

During the first stage of labor, the cervix opens (dilates) and thins out (effaces) to allow the baby to move into the birth canal. In figures A and B, the cervix is tightly closed. In figure C, the cervix is 60% effaced and 1 to 2 cm dilated. In figure D, the cervix is 90% effaced and 4 to 5 cm dilated. The cervix must be 100% effaced and 10 cm dilated before a vaginal delivery.

The first stage of labor and birth occurs when you begin to feel persistent contractions. These contractions become stronger, more regular and more frequent over time. They cause the cervix to open (dilate) and soften as well as shorten and thin (efface) to allow your baby to move into the birth canal.

The first stage is the longest of the three stages. It's actually divided into two phases — early labor and active labor.

Early labor

During early labor, your cervix dilates and effaces. You'll likely feel mild, irregular contractions.

As your cervix begins to open, you might notice a clear pink or slightly bloody discharge from your vagina. This is likely the mucus plug that blocks the cervical opening during pregnancy.

How long it lasts: Early labor is unpredictable. For first-time moms, the average length varies from hours to days. It's often shorter for subsequent deliveries.

What you can do: For many women, early labor isn't particularly uncomfortable, but contractions may be more intense for some. Try to stay relaxed.

To promote comfort during early labor:

  • Go for a walk
  • Take a shower or bath
  • Listen to relaxing music
  • Try breathing or relaxation techniques taught in childbirth class
  • Change positions

If you're having an uncomplicated pregnancy, you may spend most of your early labor at home until your contractions start to increase in frequency and intensity. Your health care provider will instruct you on when to leave for the hospital or birthing center. If your water breaks or you experience significant vaginal bleeding, call your health care provider right away.

Active labor

During active labor, your cervix will dilate from 6 centimeters (cm) to 10 cm. Your contractions will become stronger, closer together and regular. Your legs might cramp, and you might feel nauseated. You might feel your water break — if it hasn't already — and experience increasing pressure in your back. If you haven't headed to your labor and delivery facility yet, now's the time.

Don't be surprised if your initial excitement wanes as labor progresses and your discomfort intensifies. Ask for pain medication or anesthesia if you want it. Your health care team will partner with you to make the best choice for you and your baby. Remember, you're the only one who can judge your need for pain relief.

How long it lasts: Active labor often lasts 4 to 8 hours or more. On average, your cervix will dilate at approximately 1 cm an hour.

What you can do: Look to your labor partner and health care team for encouragement and support. Try breathing and relaxation techniques to relieve your discomfort. Use what you learned in childbirth class or ask your health care team for suggestions.

Unless you need to be in a specific position to allow for close monitoring of you and your baby, consider these ways to promote comfort during active labor:

  • Roll on a large rubber ball (birthing ball)
  • Take a warm shower or bath
  • Take a walk, stopping to breathe through contractions
  • Have a gentle massage between contractions

If you need to have a Cesarean delivery (C-section), having food in your stomach can lead to complications. If your health care provider thinks you might need a C-section, he or she might recommend small amounts of clear liquids, such as water, ice chips, popsicles and juice, instead of solid foods.

The last part of active labor — often referred to as transition — can be particularly intense and painful. Contractions will come close together and can last 60 to 90 seconds. You'll experience pressure in your lower back and rectum. Tell your health care provider if you feel the urge to push.

If you want to push but you're not fully dilated, your health care provider will ask you to hold back. Pushing too soon could make you tired and cause your cervix to swell, which might delay delivery. Pant or blow your way through the contractions. Transition typically lasts 15 to 60 minutes.

Stage 2: The birth of your baby

It's time! You'll deliver your baby during the second stage of labor.

How long it lasts: It can take from a few minutes to a few hours or more to push your baby into the world. It might take longer for first-time moms and women who've had an epidural.

What you can do: Push! Your health care provider will ask you to bear down during each contraction or tell you when to push. Or you might be asked to push when you feel the urge to do so.

When it's time to push, you may experiment with different positions until you find one that feels best. You can push while squatting, sitting, kneeling — even on your hands and knees.

At some point, you might be asked to push more gently — or not at all. Slowing down gives your vaginal tissues time to stretch rather than tear. To stay motivated, you might ask if you could feel the baby's head between your legs or see it in a mirror.

After your baby's head is delivered, the rest of the baby's body will follow shortly. The baby's airway will be cleared if necessary. If you've had an uncomplicated delivery, your health care provider may wait a few seconds to a few minutes before the umbilical cord is cut. Delaying clamping and cutting the umbilical cord after delivery increases the flow of nutrient-rich blood from the cord and the placenta to the baby. This increases the baby's iron stores and reduces the risk of anemia, promoting healthy development and growth.

Stage 3: Delivery of the placenta

After your baby is born, you'll likely feel a great sense of relief. You might hold the baby in your arms or on your abdomen. Cherish the moment. But a lot is still happening. During the third stage of labor, you will deliver the placenta.

How long it lasts: The placenta is typically delivered in 30 minutes, but the process can last as long as an hour.

You'll continue to have mild, less painful contractions that are close together. The contractions help move the placenta into the birth canal. You'll be asked to push gently one more time to deliver the placenta. You might be given medication before or after the placenta is delivered to encourage uterine contractions and minimize bleeding.

Your health care provider will examine the placenta to make sure it's intact. Any remaining fragments must be removed from the uterus to prevent bleeding and infection. If you're interested, ask to see the placenta.

After you deliver the placenta, your uterus will continue to contract to help it return to its normal size.

A member of your health care team may massage your abdomen. This may help the uterus contract to decrease bleeding.

Your health care provider will also determine whether you need repair of any tears of your vaginal region. If you don't have anesthesia, you'll receive an injection of local anesthetic in the area to be stitched.

Savor this special time with your baby. Your preparation, pain and effort have paid off. Revel in the miracle of birth.

Spinning Babies

Why would posterior position matter in labor?  The head is angled so that it measures larger. The top of the head molds less than the crown.

Baby’s spine is extended, not curled, so the crown of the head is not leading the way. Baby can’t help as much during the birth process to the same degree as the curled up baby.

Some posteriors are easy, while others are long and painful, and there are several ways to tell how your labor will be beforehand. After this, you may want to visit What to do when….in Labor .

Anterior and Posterior Positionss

Belly Mapping ® Method tips:  The Right side of the abdomen is almost always firmer, but the direct OP baby may not favor one side or the other. Baby’s limbs are felt in front, on both sides of the center line. A knee may slide past under the navel.

The OP position (occiput posterior fetal position) is when the back of the baby’s head is against the mother’s back. Here are drawings of an anterior and posterior presentation.

ROP

Look at the above drawing. The posterior baby’s back is often extended straight or arched along the mother’s spine. Having the baby’s back extended often pushes the baby’s chin up.

Attention: Having the chin up is what makes the posterior baby’s head seem larger than the same baby when it’s in the anterior position.

Because the top of the head enters (or tries to enter) the pelvis first, baby seems much bigger by the mother’s measurements. A posterior head circumference measures larger than the anterior head circumference.

A large baby is not the same issue, however. The challenge with a posterior labor is that the top of the head, not the crown of the head leads the way.

A baby with their spine straight has less ability to wiggle and so the person giving birth has to do the work of two. This can be long and challenging or fast and furious. Also, there are a few posterior labors that are not perceived different than a labor with a baby curled on the left.

Why? Anatomy makes the difference. Learn to work with birth anatomy to reduce the challenge of posterior labor by preparing with our Three Balances SM and more.

There are four posterior positions

The direct OP is the classic posterior position with the baby facing straight forward.   Right Occiput Transverse   (ROT) is a common starting position in which the baby has a bit more likelihood of rotating to the posterior during labor than to the anterior.   Right Occiput Posterior   usually involves a straight back with a lifted chin (in the first-time mother). Left Occiput Posterior places the baby’s back opposite the maternal liver and may let the baby flex (curl) his or her back and therefore tuck the chin for a better birth. These are generalities, of course. See a bit more about posterior positions in   Belly Mapping ® on this website. Want to map your baby’s position? Learn how with the   Belly Mapping ® Workbook .

Pregnancy may or may not show symptoms.   Just because a woman’s back doesn’t hurt in pregnancy doesn’t mean the baby is not posterior. Just because a woman is quite comfortable in pregnancy doesn’t mean the baby is not posterior. A woman can’t always feel the baby’s limbs moving in front to tell if the baby is facing the front.

The four posterior fetal positions

Four starting positions often lead to (or remain as) direct   OP   in active labor.   Right Occiput Transverse   (ROT),   Right Occiput Posterior   (ROP), and Left Occiput Posterior (LOP) join direct OP in adding labor time. The LOP baby has less distance to travel to get into an LOT position.

As labor begins, the high-riding, unengaged Right Occiput Transverse baby slowly rotates to   ROA , working past the sacral promontory at the base of the spine before swinging around to LOT to engage in the pelvis. Most babies go on to OA at the pelvic floor or further down on the perineal floor.

If a baby engages as a ROT, they may go to OP or ROA by the time they descend to the midpelvis. The OP baby may stay OP. For some, once the head is lower than the bones and the head is visible at the perineum, the baby rotates and helpers may see the baby’s head turn then! These babies finish in the ROA or OA positions.

Feeling both hands in front, in two separate but low places on the abdomen, indicates a posterior fetal position. This baby is Left Occiput Posterior.

Studies estimate 15-30% of babies are OP in labor. Jean Sutton in   Optimal Fetal Positioning   states that 50% of babies trend toward posterior in early labor upon admission to the hospital. Strong latent labor swings about a third of these to LOT before dilation begins (in “pre-labor” or “false labor”).

Recent research shows about 50% of babies are in a posterior position when active labor begins, but of these, 3/4 of them rotate to anterior (or facing a hip in an occiput transverse, head down position.

Jean Sutton’s observations, reported in her 1996 book, indicates that some babies starting in a posterior position will rotate before arriving to the hospital. Ellice Lieberman observed most posteriors will rotate out of posterior into either anterior or to facing a hip throughout labor. Only 5-8% of all babies emerge directly OP (13% with an epidural in Lieberman’s study). At least 12% of all   cesareans   are for OP babies that are stuck due to the larger diameter of the OP head in comparison to the OA head. It’s more common for ROT, ROP, and OP babies to rotate during labor and to emerge facing back (OA). Some babies become stuck halfway through a long-arc rotation and some will need a cesarean anyway.

The three anterior starting positions for labor

Why not ROA? ROA babies may have their chins up and this deflexed position may lengthen the course of labor. Less than 4% of starting positions are ROA, according to a Birmingham study. This might not be ideal for first babies, but is not a posterior position either.  

The spectrum of ease across posterior labors

Baby’s posterior position may matter in labor

With a posterior presentation, labor may or may not be significantly affected. There is a spectrum of possibilities with a posterior baby. Some women will not know they had a posterior baby because no one mentions it. Either the providers didn’t know, or didn’t notice. If labor moved along, they may not have looked at fetal position clues since there was no reason to figure out why labor wasn’t progressing. If a woman didn’t have back labor (more pain in her back than in her abdomen), the provider may not have been “clued into” baby’s position.

Some posterior babies are born in less than 8 hours and position did not slow down labor. Some posterior babies are born in less than 24 hours and position did not slow down labor enough to be out of the norm. Some posterior babies are born in less than 36-48 hours without the need for interventions.

Some posterior labors are manageable when women are mobile, supported, and eat and drink freely, as needed. Some posterior labor needs extra support that a well-trained and experienced doula may provide, but that typically a mate or loved one would not have the skills or stamina to keep up with. Some posterior labors progress only with the help of a highly-trained pregnancy bodyworker or deep spiritual, or otherwise a non-conventional model of care. Or, they seem only able to finish with medical intervention.

Some posterior labors are served by an epidural, meaning the pelvic floor relaxes enough for the baby to rotate and come out. Some epidurals, on the other hand, make it so that a woman can not finish the birth vaginally.

NOTE:   Parents should know — some birth researchers, like Pediatrician John Kennell, are seriously asking whether a mother’s epidural turns off her body’s release of pain-relieving hormones which a baby relies on during childbirth. Some babies can’t turn and can’t be born vaginally and must be born by   cesarean. This is a spectrum of possibilities. I’ve seen every one of the above possibilities several times and can add the wonderful experience of seeing a woman laughing pleasurably and squatting while her posterior baby slid out on to her bedroom floor.

Possible posterior effects, some women will have one or two and some will have many of these:

overlap.250

The forehead that overlaps the pubic bone after labor starts must turn and drop into the pelvis to allow the birth to happen naturally. A cesarean finish of the labor is possible. Look at Abdominal Lift and Tuck in Techniques to guide you to solutions for easier engagement and progress.

  • Longer pregnancy (some research shows this and some doesn’t)
  • The amniotic sac breaking (water breaks, membranes open, rupture of membranes) before labor (1 in 5 OP labors)
  • Not starting in time before induction   is scheduled
  • Labor is longer and stronger and less rhythmic than expected
  • Start and stop   labor pattern
  • The baby may not engage, even during the pushing stage
  • Longer early labor
  • Longer active labor
  • Back labor (in some cases)
  • Pitocin may be used when labor stalls (but a snoring good rest followed by oatmeal may restore a contraction pattern, too)
  • Longer pushing stage
  • Maybe a woman has all three phases of labor lengthened by the OP labor or one or two of the three phases listed
  • Sometimes the baby’s head gets stuck turned halfway to anterior – in the transverse diameter. This may be called a transverse arrest (not a   transverse lie ).
  • More likely to tear
  • More likely to need a vacuum (ventouse) or forceps
  • More likely to need a   cesarean

These effects are in comparison to a baby in the   left occiput anterior   or   left occiput transverse   fetal position at the start of labor.

Who might have a hard time with a posterior baby?

baby presentation labour

This family just had a fast posterior birth of their second child! Ease in labor includes other factors beyond baby position.

  • A first-time mom
  • A first-time mom whose   baby hasn’t dropped into the pelvis by 38 weeks gestation   (two weeks before the due date)
  • A woman with an   android pelvis   (“runs like a boy,” often long and lanky, low pubis with narrow pubic arch and/or sitz bones close together, closer than or equal to the width of a fist)
  • A woman whose baby, in the third trimester, doesn’t seem to change position at all, over the weeks. He or she kicks in the womb and stretches, but whose trunk is stationary for weeks. This mother’s broad ligament may be so tight that she may be uncomfortable when baby moves.
  • A woman who has an epidural early in labor (data supports this), before the baby has a chance to rotate and come down.
  • A woman who labors lying in bed
  • Low-thyroid, low-energy woman who has gone overdue (this is my observation)
  • A woman who lacks support by a calm and assured woman who is calming and reassuring to the birthing mother (a doula)
  • A woman put on the clock
  • A woman who refuses all help when the labor exceeds her ability to physically sustain her self (spilling ketones, dehydration, unable to eat or rest in a labor over X amount of hours which might be 24 for some or 48 for others)
  • A woman whose birth team can’t match an appropriate technique to the needs of the baby for flexion, rotation, and/or descent from the level of the pelvis where the baby is currently at when stuck

Who is likely to have an easy time with a posterior baby?

  • A second-time mom who’s given birth readily before (and pushing went well)
  • A posterior baby with a tucked chin on his or her mama’s left side with   a round pelvic brim
  • An average-sized or smaller baby
  • Someone whose posterior baby changes from right to left after doing inversions and other   balancing work , though the baby is still posterior
  • A woman with a baby in the Left Occiput Posterior, especially if the baby’s chin is tucked or flexed
  • A woman who gets bodywork, myofascial release, etc.
  • A woman whose posterior baby engages, and does not have an   android (triangular) pelvis or a small outlet
  • And of all of these, what is necessary is a pelvis big enough to accommodate the baby’s extra head size
  • A woman who uses active birthing techniques — vertical positions, moves spontaneously and instinctively or with specific techniques from Spinning Babies ® , and other good advice
  • A woman in a balanced nervous state, not so alert and “pumped up,” on guard, etc.

Any woman may also have an easier time than public opinion might indicate, too, just because she isn’t on this list. Equally, just because she is on the “hard” list doesn’t mean she will have a hard time for sure. These are general observations. They are neither condemnations nor promises. Overall, some posterior babies will need help getting born, while some posterior babies are born easily (easy being a relative term).

Let’s not be ideological about posterior labors.

While most posterior babies do eventually rotate, that can still mean there is quite a long wait – and a lot of physical labor during that wait. Sometimes it means the doula, midwife, nurse, or doctor is asking the mother to do a variety of position changes, techniques, and even medical interventions to help finish the labor. Patience works for many, but for some a   cesarean   is really the only way to be born. Read   What To Do When…in Labor .

What causes a baby to be posterior?

There is a rising incidence of posterior babies at the time of birth. We know now that epidural anesthesia increases the rate of posterior position at the time of birth from about 4% (for women who don’t choose an epidural in a university birth setting) up to about 13% (Lieberman, 2005). Low thyroid function is associated with fetal malposition such as posterior or breech. (See   Research & References .)

Most babies who are posterior early in labor will rotate to anterior once labor gets going. Some babies rotate late in labor, even just before emerging. Studies such as Lieberman’s show that at any given phase of labor, another 20% of posterior babies will rotate so that only a small number are still posterior as the head emerges.

My observations are that the majority of babies are posterior before labor. The high numbers of posterior babies at the end of pregnancy and in the early phase of labor is a change from what was seen in studies over ten years old. Perhaps this is from our cultural habits of sitting at desks, sitting in bucket seats (cars), and leaning back on the couch (slouching). Soft tissues such as the psoas muscle pair or the broad ligament also seem to be tight more often from these postures, from athletics (quick stops, jolts, and falls), from accidents, and from emotional or sexual assault.

Being a nurse or bodyworker who turns to care for people in a bed or on a table will also twist the lower uterine segment (along with some of the previously mentioned causes). This makes the baby have to compensate in a womb that is no longer symmetrical. Less often, the growing baby settles face-forward over a smaller pelvis, or a triangular-shaped pelvis (android). At the end of pregnancy, the baby’s forehead has settled onto a narrower than usual pubic bone, and if tight round ligaments hold the forehead there, the baby may have a tough time rotating. These are the moms and babies that I’m most concerned with in my work at Spinning Babies®. A baby that was   breech   beyond week 30 – 34 of pregnancy will flip head down in the posterior position. A woman with a history of breech or posterior babies is more likely to have a breech or posterior baby in the next pregnancy. However, she may not have an as long labor.

The best way to tell if your baby is OP or not, usually, is if you feel little wiggles in the abdomen right above your pubic bone. These are the fingers. They’d feel like little fingers wiggling, not like a big thunk or grinding from the head, though you might feel that, too. The little fingers will be playing by the mouth. This is the easiest indication of OP. The wiggles will be centered in the middle of your lower abdomen, close to the pubic bone. If you feel wiggles far to the right, near your hip, and kicks above on the right, but not near the center and none on the left, then those signal an   OA   or   LOT   baby (who will rotate to the OA easily in an active birth). After this, you might go to   What to do when…in Labor.

Malpresentation

8-minute read

If you feel your waters break and you have been told that your baby is not in a head-first position, seek medical help immediately .

  • Malpresentation is when your baby is not facing head-first down the birth canal as birth approaches.
  • The most common type of malpresentation is breech — when your baby’s bottom or feet are facing downwards.
  • A procedure called external cephalic version can sometimes turn a breech baby into a head-first position at 36 weeks.
  • Most babies with malpresentation are born by caesarean, but you may be able to have a vaginal birth if your baby is breech.
  • There is a serious risk of cord prolapse if your waters break and your baby is not head-first.

What are presentation and malpresentation?

‘Presentation’ describes how your baby is facing down the birth canal. The ‘presenting part’ is the part of your baby’s body that is against the cervix .

The ideal presentation is head-first, with the crown (top) of the baby’s head against the cervix, with the chin tucked into the baby’s chest. This is called ‘vertex presentation’.

If your baby is in any other position, it’s called ‘malpresentation’. Malpresentation can mean your baby’s face, brow, buttocks, foot, back, shoulder, arms or legs or the umbilical cord are against the cervix.

It’s safest for your baby’s head to come out first. If any other body part goes down the birth canal first, the risks to you and your baby may be higher. Malpresentation increases the chance that you will have a more complex vaginal birth or a caesarean.

If my baby is not head-first, what position could they be in?

Malpresentation is caused by your baby’s position (‘lie’). There are different types of malpresentation.

Breech presentation

This is when your baby is lying with their bottom or feet facing down. Sometimes one foot may enter the birth canal first (called a ‘footling presentation’).

Breech presentation is the most common type of malpresentation.

Face presentation

This is when your baby is head-first but stretching their neck, with their face against the cervix.

Transverse lie

This is when your baby is lying sideways. Their back, shoulders, arms or legs may be the first to enter the birth canal.

Oblique lie

This is when your baby is lying diagonally. No particular part of their body is against the cervix.

Unstable lie

This is when your baby continually changes their position after 36 weeks of pregnancy.

Cord presentation

This is when the umbilical cord is against the cervix, between your baby and the birth canal. It can happen in any situation where your baby’s presenting part is not sitting snugly in your pelvis. It can become an emergency if it leads to cord prolapse (when the cord is born before your baby, potentially reducing placental blood flow to your baby).

What is malposition?

If your baby is lying head-first, the best position for labour is when their face is towards your back.

If your baby is facing the front of your body (posterior position) or facing your side (transverse position) this is called malposition. Transverse position is not the same as transverse lie. A transverse position means your labour may take a bit longer and you might feel more pain in your back. Often your baby will move into a better position before or during labour.

Why might my baby be in the wrong position?

Malpresentation may be caused by:

  • a low-lying placenta
  • too much or too little amniotic fluid
  • many previous pregnancies, making the muscles of the uterus less stable
  • carrying twins or more

Often no cause is found.

Is it likely that my baby will be in the wrong position?

Many babies are in a breech position during pregnancy. They usually turn head-first as pregnancy progresses, and more than 9 in 10 babies in Australia have a vertex presentation (ideal presentation, head-first) at birth.

You are more likely to have a malpresentation if:

  • this is your first baby
  • you are over 40 years old
  • you've had a previous breech baby
  • you go into labour prematurely

How is malpresentation diagnosed?

Malpresentation is normally diagnosed when your doctor or midwife examines you, from 36 weeks of pregnancy. If it’s not clear, it can be confirmed with an ultrasound.

Can my baby’s position be changed?

If you are 36 weeks pregnant , it may be possible to gently turn your baby into a head-first position. This is done by an obstetrician using a technique called external cephalic version (ECV).

Some people try different postures or acupuncture to correct malpresentation, but there isn’t reliable evidence that either of these work.

Will I need a caesarean if my baby has a malpresentation?

Most babies with a malpresentation close to birth are born by caesarean . You may be able to have a vaginal birth with a breech baby, but you will need to go to a hospital that can offer you and your baby specialised care.

If your baby is breech, an elective (planned) caesarean is safer for your baby than a vaginal birth in the short term. However, in the longer term their health will be similar, on average, regardless of how they were born.

A vaginal birth is safer for you than an elective caesarean. However, about 4 in 10 people planning a vaginal breech birth end up needing an emergency caesarean . If this happens to you, the risk of complications will be higher.

Your doctor can talk to you about your options. Whether it’s safe for you to try a vaginal birth will depend on many factors. These include how big your baby is, the position of your baby, the structure of your pelvis and whether you’ve had a caesarean in the past.

What are the risks if I have my baby when it’s not head-first?

If your waters break when your baby is not head-first, there is a risk of cord prolapse. This is an emergency.

Vaginal breech birth

Risks to your baby can include:

  • Erb’s palsy
  • fractures, dislocations or other injuries
  • bleeding in your baby’s brain
  • low Apgar scores
  • their head getting stuck – this is an emergency

Risks to you include:

  • blood loss or blood clots
  • infection in the wound
  • problems with the anaesthetic
  • damage to other organs nearby, such as your bladder
  • a higher chance of problems in future pregnancies
  • a longer recovery time than after a vaginal birth

Risks to your baby include:

  • trouble with breathing — this is temporary
  • getting a small cut during the surgery

Will I have a malpresentation in my future pregnancies?

If you had a malpresentation in one pregnancy, you have a higher chance of it happening again, but it won’t necessarily happen in future pregnancies. If you’re worried, it may help to talk to your doctor or midwife so they can explain what happened.

Scottie Scheffler wins his second Masters, but knows priorities are about to change

baby presentation labour

AUGUSTA, Ga. — They say that the Masters doesn’t start until the back nine on Sunday, but they were wrong today. 

This Masters started and then quickly ended one hole earlier, on the ninth green, where five minutes of late-afternoon drama changed everything for the now two-time Masters champion, Scottie Scheffler. 

Scheffler came to the ninth tee tied for the lead with his playing partner, fellow 27-year-old American Collin Morikawa. But when he walked off the green on his way to the 10th tee, he was the fortunate owner of a three-shot lead.

His dominance only built from there, as the 2022 Masters champion coasted to the 2024 Masters title with four more birdies on the back nine to run his winning score to 11-under par , four strokes ahead of runner-up Ludvig Åberg of Sweden. 

Scheffler’s march to victory was decidedly different than the last time he did this two years ago, when his emotions exploded on the 18th green in an embarrassing four-putt, even though he still managed to defeat Rory McIlroy by three strokes. 

This time, he was all business.

“I tried not to let my emotions get the best of me this time,” Scheffler said. “I kept my head down. I don't think I even took my hat off and waved to the crowd walking up 18. I did my best to stay in the moment, and I wanted to finish off the tournament in the right way. And I got to soak it in there after 1-putting instead of 4-putting, which was a little bit better.”

More Masters: After finishing last at Masters, Tiger Woods looks ahead to three remaining majors

Scheffler is a cool customer, as steady and determined (and talented) a player as there is in the game of golf at the moment. But under that calm exterior, a fierce competitor lurks.

“I love winning,” he said. “I hate losing. I really do. And when you're here in the biggest moments, when I'm sitting there with the lead on Sunday, I really, really want to win badly.”

Nowhere was that more evident than when he stood down the hill from the ninth green, little more than 100 yards from the pin, with a lob wedge in his hands. His approach hit behind the flagstick and then spun backwards toward the hole, rolling and rolling as hundreds of spectators rose to their feet in giddy anticipation, believing something spectacular was about to happen. 

It turns out the ball did not fall off the face of the earth into the hole, but it certainly came close, stopping just a couple of inches away. The tap-in birdie took Scheffler to 8-under par for the tournament and gave him a momentary one-stroke lead over Morikawa.

But that was about to change. After Scheffler’s heroics, Morikawa peered out from the bottom of the glistening bunker at the front left of the green, standing over his ball. He needed to get it close to stay within one stroke of Scheffler but instead, disaster struck: the ball failed to clear the edge of the bunker and rolled back into the sand. Morikawa took another swing at it and sent the ball onto the green, but then missed his putt to settle for a double bogey 6. 

This all transpired on the ninth green in five minutes, from 4:40 to 4:45 p.m. on Sunday afternoon. No one knew it yet, but with the wind in his sails, the Masters was ostensibly over as Scheffler was never seriously challenged by anyone again.

“I feel like playing professional golf is an endlessly not satisfying career,” he said after it all was over. “For instance, in my head, all I can think about right now is getting home. I'm not thinking about the tournament. I'm not thinking about the green jacket.

“I wish I could soak this in a little bit more. Maybe I will tonight when I get home. But at the end of the day, I think that's what the human heart does. You always want more, and I think you have to fight those things and focus on what's good.”

Most immediately, that’s the birth of his first child, a topic of much discussion here this week when he said he would leave the course at any moment if his wife Meredith went into labor. His life — their life — is about to change forever, he knows.

“I will go home, soak in this victory tonight,” he said. “I will definitely enjoy the birth of my first child. But with that being said, I still love competing. My priorities will change here very soon. My son or daughter will now be the main priority, along with my wife, so golf will now be probably fourth in line. 

“But I still love competing. I don't plan on taking my eye off the ball anytime soon, that's for sure.”

Fetal Presentation, Position, and Lie (Including Breech Presentation)

  • Variations in Fetal Position and Presentation |

During pregnancy, the fetus can be positioned in many different ways inside the mother's uterus. The fetus may be head up or down or facing the mother's back or front. At first, the fetus can move around easily or shift position as the mother moves. Toward the end of the pregnancy the fetus is larger, has less room to move, and stays in one position. How the fetus is positioned has an important effect on delivery and, for certain positions, a cesarean delivery is necessary. There are medical terms that describe precisely how the fetus is positioned, and identifying the fetal position helps doctors to anticipate potential difficulties during labor and delivery.

Presentation refers to the part of the fetus’s body that leads the way out through the birth canal (called the presenting part). Usually, the head leads the way, but sometimes the buttocks (breech presentation), shoulder, or face leads the way.

Position refers to whether the fetus is facing backward (occiput anterior) or forward (occiput posterior). The occiput is a bone at the back of the baby's head. Therefore, facing backward is called occiput anterior (facing the mother’s back and facing down when the mother lies on her back). Facing forward is called occiput posterior (facing toward the mother's pubic bone and facing up when the mother lies on her back).

Lie refers to the angle of the fetus in relation to the mother and the uterus. Up-and-down (with the baby's spine parallel to mother's spine, called longitudinal) is normal, but sometimes the lie is sideways (transverse) or at an angle (oblique).

For these aspects of fetal positioning, the combination that is the most common, safest, and easiest for the mother to deliver is the following:

Head first (called vertex or cephalic presentation)

Facing backward (occiput anterior position)

Spine parallel to mother's spine (longitudinal lie)

Neck bent forward with chin tucked

Arms folded across the chest

If the fetus is in a different position, lie, or presentation, labor may be more difficult, and a normal vaginal delivery may not be possible.

Variations in fetal presentation, position, or lie may occur when

The fetus is too large for the mother's pelvis (fetopelvic disproportion).

The uterus is abnormally shaped or contains growths such as fibroids .

The fetus has a birth defect .

There is more than one fetus (multiple gestation).

Position and Presentation of the Fetus

Variations in fetal position and presentation.

Some variations in position and presentation that make delivery difficult occur frequently.

Occiput posterior position

In occiput posterior position (sometimes called sunny-side up), the fetus is head first (vertex presentation) but is facing forward (toward the mother's pubic bone—that is, facing up when the mother lies on her back). This is a very common position that is not abnormal, but it makes delivery more difficult than when the fetus is in the occiput anterior position (facing toward the mother's spine—that is facing down when the mother lies on her back).

When a fetus faces up, the neck is often straightened rather than bent,which requires more room for the head to pass through the birth canal. Delivery assisted by a vacuum device or forceps or cesarean delivery may be necessary.

Breech presentation

In breech presentation, the baby's buttocks or sometimes the feet are positioned to deliver first (before the head).

When delivered vaginally, babies that present buttocks first are more at risk of injury or even death than those that present head first.

The reason for the risks to babies in breech presentation is that the baby's hips and buttocks are not as wide as the head. Therefore, when the hips and buttocks pass through the cervix first, the passageway may not be wide enough for the head to pass through. In addition, when the head follows the buttocks, the neck may be bent slightly backwards. The neck being bent backward increases the width required for delivery as compared to when the head is angled forward with the chin tucked, which is the position that is easiest for delivery. Thus, the baby’s body may be delivered and then the head may get caught and not be able to pass through the birth canal. When the baby’s head is caught, this puts pressure on the umbilical cord in the birth canal, so that very little oxygen can reach the baby. Brain damage due to lack of oxygen is more common among breech babies than among those presenting head first.

In a first delivery, these problems may occur more frequently because a woman’s tissues have not been stretched by previous deliveries. Because of risk of injury or even death to the baby, cesarean delivery is preferred when the fetus is in breech presentation, unless the doctor is very experienced with and skilled at delivering breech babies or there is not an adequate facility or equipment to safely perform a cesarean delivery.

Breech presentation is more likely to occur in the following circumstances:

Labor starts too soon (preterm labor).

The uterus is abnormally shaped or contains abnormal growths such as fibroids .

Other presentations

In face presentation, the baby's neck arches back so that the face presents first rather than the top of the head.

In brow presentation, the neck is moderately arched so that the brow presents first.

Usually, fetuses do not stay in a face or brow presentation. These presentations often change to a vertex (top of the head) presentation before or during labor. If they do not, a cesarean delivery is usually recommended.

In transverse lie, the fetus lies horizontally across the birth canal and presents shoulder first. A cesarean delivery is done, unless the fetus is the second in a set of twins. In such a case, the fetus may be turned to be delivered through the vagina.

Scottie Scheffler would withdraw from Masters and 'be out of here' if wife goes into labor

baby presentation labour

Scottie Scheffler 's sister Sara caddied for him Wednesday, as his wife is home waiting for their first child to be born.

When asked by the broadcast if he would withdraw from the tournament should his wife go into labor early, Scheffler responded: "I'll be out of here."

"I think first child wins over quite a... over many things in my life," Scheffler said mid-put during the Par 3 contest .

Scheffler, the 2022 Masters champion and favorite for the 2024 tournament, is expecting his first child with his wife Meredith in the next few weeks. Meredith was unable to make the trip to Augusta, according to Scheffler.

"Meredith is resting up, we're a few weeks away," Scheffler said. "We could not get the OK from the doctor."

Scheffler isn't the only Masters competitor on baby watch. Sam Burns is also nearing the birth of his first child, with wife Caroline due in just over a week.

Who is Scottie Scheffler's wife?

Scottie Scheffler's wife is Meredith Scheffler, formerly Meredith Scudder.

Growing up in Dallas, the two were high school sweethearts at Highland Park High School. After six years of dating — four including four with  Scottie Scheffler attending the University of Texas to play golf  and Meredith Scheffler attending Texas A&M — the couple got married in 2020. Meredith Scheffler was on the bag for Scottie Scheffler at one point of the 2022 Masters Tournament — one that he won — and then again during the Par 3 contest in 2023. 

Meredith Scheffler is the  Director of Curating Opportunities  at  Behind Every Door (BED) , a non-profit organization in Dallas that provides youth in underdeveloped neighborhoods in the Dallas area with sports, educational, and creative programs.
