Topic Overview
What is breech position?
During most of pregnancy,
there is enough room in the
uterus for the baby (fetus) to
change position. By 36 weeks of pregnancy, most babies turn into a head-down
position. This is the normal and safest fetal position for birth.
But in about 4 out of 100 births, the baby does not naturally turn
head-down late in the pregnancy. Instead, the baby is in a breech
position.1 Babies in breech position usually must be
delivered by
C-section.
There are three main breech
positions:
-
Frank breech. The
buttocks are in place to come out first during delivery. The legs are straight
up in front of the body, with the feet near the head. This is the most common
type of breech position.
-
Complete breech.
The buttocks are down near the birth canal. The knees are bent, and the feet
are near the buttocks.
-
Footling breech. One
leg or both legs are stretched out below the buttocks. The leg(s) are in place
to come out first during delivery.

What causes breech position during pregnancy?
In
more than half of breech births, there is no clear reason why the baby did not
turn head-down.2 In other cases, breech position might
be linked to:3
- Labor that begins before the 37th week of
pregnancy, before the baby is likely to turn head-down on its
own.
- Twins or more. Limited space for two or more babies can
prevent them from moving into the head-down position before
delivery.
- Too much or too little
amniotic fluid in the uterus.
- Problems
with the uterus, such as an oddly shaped uterus or
uterine fibroids, which are noncancerous growths in
the uterine wall.
- Stretched and weakened uterine muscle from past
pregnancies.
- Problems with the baby, including heart, digestive
tract, and brain problems, such as
Down syndrome,
anencephaly, or
hydrocephalus.
What are the signs that your baby is in breech position?
You probably will not be able to feel whether your baby is breech. But if
you are 36 or more weeks pregnant and think you feel the baby’s head pressing
high up in your belly and/or you feel kicking in your lower belly, see your
doctor for an exam.
How is a breech position diagnosed?
During a
routine exam late in your pregnancy, your doctor will feel your upper and lower
belly and may do a
fetal ultrasound to find out if your baby is breech.
Your doctor may also learn that your baby is breech when he or she checks your
cervix.
How is breech position treated?
Sometimes it is
possible for a doctor to turn a baby from a breech position to a head-down
position by using a procedure called an
external cephalic version. If the baby can be turned
head-down before labor starts, you may be able to have a vaginal birth.
You also can ask your doctor if you can try certain positions at home
that may help turn your baby. There is no research to prove that this works,
but it’s not harmful. It may work for you.
It’s normal to feel
disappointed and worried about a breech pregnancy, especially if the doctor has
tried to turn the baby without success. But most breech babies are healthy and
do not have problems after birth. Talk to your doctor if you're concerned about
your baby’s health.
How is a breech baby delivered safely?
Most of the
time a planned cesarean delivery (C-section) is safest for the baby. But
sometimes it is possible to have a planned vaginal delivery with a breech
birth. Talk to your doctor about how to have the safest delivery for your
breech baby.
If you are using a midwife and your baby is in breech
position, your midwife will refer you to a doctor for a C-section or vaginal
breech delivery.
No matter what position a baby is in, every labor
and delivery is unique. Even though you and your doctor have a birth plan for
labor and delivery, plans can change. If something unexpected happens, your
doctor may need to make some quick decisions to keep you and your baby
safe.
