High-Risk Obstetrics, Fetal Malpresentation, Menopause Center of Los AngelesAs the baby reaches the final stages of pregnancy, it moves into position for delivery. If the mother is lying on her back, the most common and safest birth presentation for the baby is:

  • Facing downward
  • Coming out headfirst
  • Tucking its chin into its chest
  • Folding its arms across the chest
  • Angling its face and body to the right or left of the mother’s spine

There are many variations on this position, which are called malpresentation or abnormal presentations. Your doctor can sometimes correct the baby’s presentation, but in some cases it’s safest to deliver via C-section.

Breech Presentation

A baby in breech presentation is coming out bottom-first or feet-first. Breech babies can sometimes be cross-legged, or have their feet reaching up toward their head. The doctor may be able to adjust the baby’s position before labor begins, by strategically pressing on the abdomen with ultrasound as a guide. This can be uncomfortable, so it is usually performed under regional anesthesia. If this doesn’t work, a Cesarean delivery may be recommended.

Face Up

Babies exiting the womb head first, but facing up, toward the mother’s bellybutton, are in the occiput posterior position. Maternity care providers call this position “sunny side up.” Most of the time, uterine contractions or the mother’s pushing will rotate the baby to face down. If they don’t, the mother might experience longer labor, more back pains, and difficulty pushing the baby out.

Transverse Presentation

In most pregnancies, the baby will end up with its spine vertical in the womb. Some, however, are lying horizontally, or “transverse,” in the womb. This position makes vaginal delivery extremely unsafe.  The doctor may try to adjust the baby’s positioning before labor, or recommend a Cesarean delivery.

Compound Presentation

Breech Presentations, Transverse Presentation, Malpresentation, Menopause Center of Los AngelesWhen a baby’s hand or foot is presented alongside the baby’s head or bottom, this is called compound presentation. We can’t usually predict if the baby present this way until the mother starts pushing. Luckily, compound presentation is not a cause for concern, and most babies presenting this way can continue on their way without issue.

Face/Brow Presentation

When the baby’s neck is outstretched, and its chin is pointing away from its chest, its face or brow will present first. This presentation is fairly rare, but when it does happen, labor can take a little longer. The newborn’s face and head may be swollen or bruised for a few days. Most of the time, this presentation can be delivered vaginally, but occasionally a C-section is required.

Shoulder Dystocia

Shoulder dystocia occurs when the baby’s head has exited the birth canal, but its shoulders get stuck on the pelvic bone. It’s hard to predict when this may happen, but if it does, it is considered a medical emergency.

Your doctor may need to manually adjust the baby in order to free its shoulders. In the best-case scenario, the maneuvering works and the baby is delivered, vaginally and with no harm. Occasionally, the baby is injured in the process. It’s rare for a C-section to be performed in this case.
