A breech birth is when a baby is positioned feet-first or bottom-first in the uterus instead of the usual head-down position at the time of delivery. About 3 to 4 percent of full-term pregnancies involve a breech presentation, making it one of the most common reasons for a planned cesarean section. Most babies settle into a head-down position on their own by the third trimester, but when they don’t, parents face a set of decisions about how to proceed.
Types of Breech Positioning
Not all breech presentations look the same inside the uterus, and the type matters because it affects delivery options.
- Frank breech: The baby’s bottom is closest to the birth canal, with the legs folded straight up against the head. This is the most common type and generally the most favorable for vaginal delivery if one is attempted.
- Complete breech: Both knees are bent so that the feet and bottom are near the birth canal, almost like the baby is sitting cross-legged.
- Footling breech: One or both feet dangle below the bottom, pointing toward the birth canal. This carries the highest risk during vaginal delivery because a foot or leg can slip through the cervix before it’s fully dilated.
- Incomplete breech: One knee is bent with one foot and the bottom near the birth canal, while the other leg is extended.
Why Some Babies Stay Breech
Earlier in pregnancy, breech positioning is extremely common. Between 22 and 25 percent of babies are breech before 28 weeks, dropping to 7 to 15 percent at 32 weeks as they naturally flip head-down. By full term, only 3 to 4 percent remain breech. Several factors can make it harder for a baby to turn:
- Premature birth: The baby simply hasn’t had enough time to rotate.
- Multiple pregnancies: Twins or more leave less room for movement.
- Uterine shape or growths: An irregularly shaped uterus or fibroids can restrict the baby’s ability to turn.
- Placenta previa: When the placenta covers part or all of the cervical opening, it can block the baby’s path to a head-down position.
- Previous pregnancies: Having been pregnant before slightly increases the chance of breech, possibly because the uterine walls are more relaxed and give the baby more room to settle in an unusual position.
- Certain birth defects: Occasionally, structural differences in the baby can prevent the typical rotation.
In many cases, though, there’s no identifiable reason. The baby just doesn’t turn.
How Breech Is Detected
Your provider will check your baby’s position in the weeks leading up to your due date, typically through a hands-on technique called Leopold’s maneuvers, where they press on different areas of your abdomen to feel for the baby’s head, back, and bottom. This method catches most breech presentations, but it’s not perfect. Studies have found its sensitivity is around 75 percent, meaning roughly one in four breech babies can be missed by touch alone.
Ultrasound is far more reliable. Research suggests that routine bedside ultrasound in late pregnancy significantly reduces the number of surprise breech presentations discovered only during labor. Some experts have recommended standardizing ultrasound checks at 36 weeks to make sure breech positioning is caught early enough to discuss options.
Turning the Baby: External Cephalic Version
If your baby is still breech around 37 weeks, your provider may offer a procedure called external cephalic version, or ECV. During this procedure, the doctor places their hands on your abdomen and applies firm, steady pressure to physically rotate the baby into a head-down position. Nothing is inserted vaginally. The whole process, including monitoring before and after, takes about two hours.
ECV has an average success rate of about 58 percent, so it works a little more than half the time. The pressure can cause cramping, and the procedure is only performed in a setting where a cesarean can be done quickly if complications arise. When it works, it opens the door to a standard vaginal delivery. When it doesn’t, or when there are reasons it can’t be attempted (such as placenta previa or certain pregnancy complications), the conversation shifts to planning the birth itself.
Delivery Options for Breech Babies
For most breech babies at full term, a planned cesarean section is the standard recommendation. The American College of Obstetricians and Gynecologists notes that cesarean delivery is the preferred mode for most physicians, largely because expertise in vaginal breech delivery has declined significantly over the past two decades. Fewer doctors are trained in the technique, and fewer hospitals have protocols in place for it.
That said, vaginal breech delivery isn’t off the table entirely. ACOG states that a planned vaginal delivery of a breech baby “may be reasonable” when a hospital has specific protocols and the provider has the necessary experience. If you’re considering this route, expect a detailed informed consent discussion. The evidence shows that the risk of serious complications for the baby is somewhat higher with vaginal breech delivery compared to a planned cesarean, which is the primary reason the surgical option became dominant.
The decision also depends on the type of breech. A frank breech, where the baby’s bottom leads and legs are folded up, is considered the most manageable for vaginal delivery. Footling breech carries more risk and is rarely attempted vaginally.
Recovery Differences for the Mother
Because most breech babies are delivered by cesarean, it’s worth understanding how recovery compares. In large studies, serious maternal complications (heavy bleeding, fever, wound problems) occurred at similar rates for both planned cesarean and planned vaginal breech deliveries: about 3.9 percent versus 3.2 percent, a difference that wasn’t statistically significant.
The recovery experience does differ in character, though. At three months postpartum, women who had a planned cesarean were more likely to report abdominal pain, which makes sense given the surgical incision. Women who delivered vaginally were more likely to report perineal pain. Planned cesarean was also associated with a lower rate of gas incontinence at the three-month mark. These tradeoffs are worth discussing with your provider when weighing your options.
Hip Screening for Breech Babies
One thing many parents don’t expect after a breech birth is extra attention to their baby’s hips. Breech positioning is a known risk factor for developmental dysplasia of the hip (DDH), a condition where the hip joint doesn’t form properly. The baby’s position in the womb, particularly with legs extended upward in a frank breech, can put unusual stress on the hip socket.
The American Academy of Pediatrics recommends hip imaging (usually an ultrasound at around 6 weeks of age) for all girls born in the breech position, regardless of whether anything seems abnormal on physical exam. For boys born breech and girls with a family history of hip dysplasia, imaging is considered optional but worth discussing. DDH is highly treatable when caught early, typically with a soft brace worn for several weeks, so this screening is a straightforward precaution rather than a cause for alarm.
