Breech presentation means your baby is positioned bottom-first or feet-first in the uterus instead of the usual head-down position. About 24% of babies are breech at 28 weeks of pregnancy, but most turn on their own before delivery. By 37 weeks, only about 3.7% remain breech.
Types of Breech Position
Not all breech presentations look the same. The differences come down to how the baby’s legs are positioned, and the type matters because it affects delivery options.
In a frank breech, the baby’s hips are bent and the legs extend straight up so the feet are near the face, like a pike position. This is the most common type. A complete breech is more like a sitting position, with both hips and knees bent and the legs tucked underneath. An incomplete or footling breech has one or both legs dangling down toward the birth canal. A single footling breech means one leg is extended downward; a double footling means both are.
Why Some Babies Stay Breech
Most babies naturally rotate to a head-down position by the third trimester. When they don’t, several factors can play a role. An unusually shaped uterus can limit the space available for the baby to turn. Too much or too little amniotic fluid also changes how easily the baby can move. The location of the placenta matters as well: a placenta sitting low in the uterus (placenta previa) can physically block the baby from flipping. Prematurity is another major factor, simply because smaller, younger babies haven’t yet settled into their final position. Multiple pregnancies, a history of prior breech deliveries, and certain uterine fibroids can all increase the likelihood.
How Breech Is Diagnosed
Your provider will typically check your baby’s position during routine prenatal visits in the third trimester using a hands-on technique called Leopold maneuvers. This involves four steps of pressing gently on different areas of your abdomen to feel where the baby’s head, back, and bottom are located. The first step checks whether the head or the bottom is at the top of the uterus. The second identifies where the spine and limbs are. The third and fourth steps assess what part of the baby is sitting lowest, near your pelvis.
Experienced providers can often identify a breech baby this way, but ultrasound is the gold standard for confirming it. Whenever there’s even slight suspicion that the baby isn’t head-down, an ultrasound is recommended.
Turning a Breech Baby
If your baby is still breech around 36 to 37 weeks, your provider will likely discuss an external cephalic version, or ECV. This is a procedure where a doctor places hands on your abdomen and physically guides the baby into a head-down position. It’s done in a hospital setting, typically with medication to relax the uterus, and with monitoring equipment ready in case a cesarean becomes necessary.
The average success rate is about 58%, meaning it works a little more than half the time. ECV is less likely to be offered if you have low amniotic fluid, vaginal bleeding, placenta previa, an irregularly shaped uterus, high blood pressure, diabetes, or if you’re carrying multiples. An abnormal fetal heart rate pattern is also a reason to skip the procedure.
Alternative Approaches
Some parents try complementary techniques to encourage the baby to turn. Moxibustion, a traditional Chinese practice that involves burning an herb near a specific acupuncture point on the little toe, has the most research behind it. A Cochrane review of seven trials involving over 1,100 women found that moxibustion combined with standard care probably reduces the chance of the baby remaining breech at birth by about 13%. However, it didn’t meaningfully lower the overall cesarean rate.
Postural techniques, where you spend time in positions like kneeling with your chest low and hips elevated, are widely discussed online. A Cochrane review found insufficient evidence that these positions actually change breech presentation or reduce cesarean rates. They’re generally considered low-risk, but the science doesn’t strongly support them as effective on their own.
Delivery Options for Breech Babies
The biggest decision after a breech diagnosis is how to deliver. Current guidelines from both the American College of Obstetricians and Gynecologists and the Royal College of Obstetricians and Gynaecologists acknowledge that planned cesarean delivery has short-term safety advantages for breech babies. A landmark international trial comparing planned cesarean with planned vaginal breech birth found that serious complications for the newborn occurred in 1.6% of cesarean deliveries versus 5% of vaginal deliveries. That’s a meaningful difference in the short term.
Importantly, when researchers followed up on those same children later, the rate of death or developmental delay was essentially the same in both groups, around 3%. So the long-term outcomes were similar regardless of delivery method.
Vaginal breech birth is not off the table entirely. Both major guidelines say it can be reasonable when a hospital has specific protocols in place and when the delivering provider has experience with breech births. The frank breech position is generally considered the most favorable for a vaginal attempt, while footling breech carries higher risk because of the greater chance that the umbilical cord can slip past the baby’s legs and into the birth canal before delivery is complete. This complication, called cord prolapse, occurs in slightly more than 1% of breech presentations.
The reality is that vaginal breech births have become uncommon enough that many obstetricians have limited hands-on experience with them. This loss of skill is itself a recognized concern in obstetric training. If vaginal breech delivery is something you want to explore, the conversation should include a frank discussion of your provider’s experience and your hospital’s capabilities.
What Breech Means for Outcomes
Babies who present breech at term tend to have slightly worse outcomes than head-down babies regardless of how they’re delivered. This isn’t entirely explained by the delivery itself. Some of the same factors that cause a baby to remain breech, such as uterine abnormalities or growth issues, may independently contribute to complications. A cesarean delivery reduces but doesn’t eliminate this difference.
For the mother, cesarean delivery carries its own set of trade-offs. Recovery takes longer, and repeated cesareans in future pregnancies increase the risk of serious placental complications. This is part of why the decision isn’t as simple as defaulting to surgery every time. Your individual circumstances, including whether you plan future pregnancies, factor into what makes the most sense.
