Answer
Absolutely not. First of all, it is very common for babies to be in the
breech position prior to 28 weeks gestation. In fact, about 7% of babies
are in breech position at 32 weeks gestation, but only about 3% go into
labor that way.
There are some uncommon birth defects which can cause breech
presentations, but more frequently it is idiopathic (meaning nothing
wrong), or due to obstructions in the uterus like fibroids or the
placenta getting in the way.
Breech presentations come in three types: frank breech (legs straight
up toward the head); complete breech (legs folded); and incomplete, or
footling (like a complete, but with a foot leading the way). While all
could potentially be delivered vaginally, the frank breech is the
safest to deliver that way.
Many times an external cephalic version (ECV) can be attempted at 36-38
weeks gestational age. This is a procedure where the mother is mildly
sedated and an attempt is made to turn the baby by pushing on the
mother's abdomen. This is successful 70-80% of the time, but runs the
risk of causing fetal distress and a possible cesarean section.
Babies who are delivered after a breech presentation should have their
hips checked carefully for potential hip dislocation.
