What Does It Mean to Have a Frank Breech Baby?

Frank breech is the most common type of breech position. Learn what this position means for you and your baby.

If your baby is in a frank breech position, that means that their bottom is facing down towards the birth canal instead of their head. The part of the baby that is nearest to the cervix is called the presenting part. The presenting part, which is the part of the baby's body that is born first in a vaginal delivery, is usually the baby's head (known as vertex presentation).

In a small number of deliveries, however, a baby’s bottom or feet are in a position to be born first. This is called a breech presentation, and frank breech (bottom first, with feet up near the head) is the most common type.

Learn about the types of breech presentation including frank breech, what causes a baby to be breech, how it's treated, and what to expect with a breech delivery.

Frank Breech and Other Types of Breech Positions

Babies can be in all sorts of positions during pregnancy, but most babies eventually turn head down in late pregnancy. As pregnancy progresses, the more likely it is that the baby will turn and the head will be down near the cervix when it's time for delivery.

Breech Presentation Statistics

  • Before the 28th week of pregnancy, about 20% to 25% of babies are breech.
  • By the 34th week of pregnancy, most babies will turn and approximately 5% to 7% will be breech.
  • By full term, only 3% to 4% of babies (3 or 4 out of every 100 births) are breech.

Sometimes, however, babies are in a breech (bottom or leg down) position when labor begins. There are several types of breech positions.

Frank breech

A frank breech position is when the baby’s bottom is down, but their legs are straight up with their feet near their head. The presenting part is the buttocks.

A frank breech is the most common breech presentation, especially when a baby is born at full term. Of the 3% to 4% of term breech births, babies are in the frank breech position 50% to 70% of the time.

Complete breech

In this position, the bottom is down, but the baby's knees are also bent, so the feet are also down near the buttocks. The presenting part is not only the bottom but both feet as well. At delivery, about 10% of breech babies are in a complete breech position.

Incomplete (footling) breech

A footling breech position is when the baby’s legs are extended and facing straight down. Instead of the bottom, the presenting part is one foot (a single footling) or both feet (a double footling). Approximately 25% of breech deliveries are incomplete.

How To Tell If Your Baby Is Breech

As your pregnancy progresses, your prenatal health care provider will examine you and keep track of your baby’s position. You might even be able to figure out how your baby is positioned on your own.

Here are some of the techniques you and your health care provider can use to tell which way your baby is facing.

  • Kicks: You can feel where your baby is kicking you and judge their general position. If you feel kicks in your lower pelvis, then the baby hasn’t turned head down yet. But if the kicks are up toward your ribs and the top of your uterus, then the baby’s head is most likely facing down.
  • Palpation: At your prenatal visits, your doctor or midwife will check your baby's position by palpating or feeling your belly to find the baby’s head, back, and bottom.
  • Heartbeat: Listening to the baby’s heartbeat is another way to tell where your baby is in the uterus. By finding the heartbeat's location, the doctor or midwife can get a better idea of the baby’s position.
  • Ultrasound: An ultrasound provides the best position information. It shows you and your health care team a picture of the baby and their exact position in your uterus. If your baby is breech, the ultrasound can determine the type of breech position your baby is in, such as frank breech or complete breech.
  • Pelvic exam: During labor, your health care provider can perform a pelvic examination. They will be able to feel whether the baby’s head or their bottom and feet are in the birth canal.

Causes of Breech Presentations

The size of the baby, amount of amniotic fluid, and amount of space inside the uterus are all factors that can contribute to a baby’s ability to move around.

The most common reason for a breech presentation is prematurity, but other factors could lead to a baby in a breech position:

  • Premature delivery: A premature baby is smaller and has more room inside the uterus to move around, which increases the chances that they will be in a breech presentation if you go into preterm labor.
  • Multiples: Twins or other multiples have less room in the uterus to move around and get into the head-down position for delivery.
  • Uterine issues: Fibroids or a heart-shaped uterus can get in the way of the baby’s ability to turn.
  • Shortened umbilical cord: If the umbilical cord is very short, the baby may not be able to move and turn.
  • Too much or too little amniotic fluid: Too much amniotic fluid gives the baby the ability to move around freely in the uterus. As they grow, they may still be able to flip and turn rather than turning head down and staying head down. Too little amniotic fluid, on the other hand, may prevent a baby from moving into the head-down position as they get closer to full-term.
  • Location of the placenta: When the placenta is low and covers all or part of the cervix, it’s called placenta previa. When the placenta is in this position, it takes up the room at the bottom of the uterus and can make it difficult for the baby to turn head down.
  • Congenital abnormalities in the baby: Some congenital abnormalities can affect the baby’s ability to move into the head-down position. These conditions are usually not a surprise at delivery since they are typically seen during prenatal ultrasound examinations.

Treatment for Breech Presentations

If your baby is breech, you will face four possible outcomes to your pregnancy:

  • Your baby may turn on its own. Especially if it's early in your pregnancy, there is a chance your baby will turn from a breech position to a head-down position. Many prenatal health care providers will take a wait-and-see approach early on.
  • Your doctor may attempt to manually turn your baby. If there are no complications in your pregnancy and the baby has not yet turned on its own by the 36th or 37th week, your doctor may attempt to turn the baby using a manual procedure called external cephalic version (ECV). ECV works approximately 60% of the time.
  • Your doctor may schedule a C-section. For a baby that remains in a breech position in late pregnancy, most doctors will recommend a surgical birth via a C-section.
  • Your doctor may agree to help you attempt a vaginal delivery. The majority of pregnancy care providers will not deliver a breech baby vaginally, but a small percentage of doctors may be willing to work with you having a vaginal delivery with a breech baby.

You can also do some things to encourage your baby to turn head down, such as acupuncture and exercises like pelvic tilts and even walking.

Complications of a Breech Birth

Most babies who are born breech are healthy. But when a baby is frank breech or in any other breech position, there is a higher chance of a complicated labor and delivery. Here are some of the complications associated with breech birth.

Umbilical cord prolapse

During a vaginal breech delivery, there is a chance that the umbilical cord will come down through the cervix before the baby is born. As the baby comes through the birth canal, their body and head can press on the cord and cut off the supply of blood and oxygen that the cord is carrying.

This can affect the baby’s heart rate and the flow of oxygen and blood to the baby’s brain. The danger of a prolapsed cord is greater with a footling breech and a complete breech.

The risk of cord prolapse is less when the baby is in the frank breech position.

Head entrapment

The baby’s head can get stuck during the delivery if the baby’s body is born before the cervix fully dilates. This situation is dangerous since the head can press against the umbilical cord and cause asphyxia or a lack of oxygen.

Head entrapment is more common in premature deliveries because the baby’s head is typically bigger than their body.

Physical injuries to the baby

The risk of injury to the baby during delivery is higher when the baby is breech compared to when the baby is not breech. Preemies are more likely to injure their head and skull. Bruising, broken bones, and dislocated joints can also occur depending on the baby's position during birth.

Additionally, after a baby is born, breech newborns have a higher incidence of neonatal hip instability, also called developmental dysplasia of the hip (DDH). This complication occurs in between 12% to 24% of breech babies.

Physical injury to the gestational parent

The vaginal delivery of a breech baby can require an episiotomy and the use of forceps, which can cause injury to the birthing person's genital area.

What Happens If My Baby Is Breech?

Many babies will turn to the head-down position before labor begins. However, if your baby is still breech when labor begins, you and your doctor will have to decide between having a C-section or trying a vaginal birth.

Whenever possible, the standard choice is to deliver any breech baby who is premature or in distress via cesarean section. Since vaginal deliveries, even when all the above criteria are met, come with a higher risk of a difficult birth and birth injuries, most doctors prefer to deliver all breech presentations by C-section.

However, when there are no other complications, a baby in the frank breech position may be delivered vaginally if the doctor agrees to it and certain conditions are met:

  • Emergency resources are available
  • The baby is at least 36 weeks
  • The baby is not too big or too small
  • The baby’s head is in the right position (flexed)
  • The health care team has experience with breech deliveries
  • The size of your pelvis is large enough
  • There is continuous monitoring of the baby
  • You have delivered vaginally before

If any complications arise during the delivery, you may still need an emergency C-section.
