Breech during Pregnancy
As pregnancy continues, usually a baby turns into the head first position. Near the due date, only about three babies in every hundred are breech. Most babies are lying head first ready to be born.
Breech presentation may be more common if you have:
a low-lying placenta
lax muscles of the uterus (usually due to having a number of babies)
too much, or too little, amniotic fluid (waters) around the baby
an uncommon shape of the uterus, or large fibroids
previous breech presentation
twins
If a baby is found to be in a breech position near the due date, an ultrasound will be performed to try to identify the reason. Most commonly though, no specific cause is found.
