While the majority of births go pretty smoothly, a variety of complications can occur.

Most babies are born head first, but when a baby's ready to come out feet-first, it's called a breech birth or breech baby. New Mom Teresa McGinnis says, "Dr. Bloy at one of my regular visits told me that the baby hadn't turned yet."

Obstetrician Dr. Richard Bloy explains, "It's pretty common, it happens in at least 20% of pregnancies up to about 30 weeks."

Dr. Bloy says that breech deliveries can be dangerous for both the mother and child. "The heads bigger than the body. So if the body comes out first the head can become trapped, that's our biggest concern."

Many babies are breech early in pregnancy, but most of them turn to the headfirst position near the end of the pregnancy. Teresa says "I just decided I'll wait and see what happens by 36-weeks. I figured he would turn by then. I was hoping he would."

But Owen wasn't turning and as his due date was nearing. Dr. Bloy told Teresa he could turn her baby by performing something called an external version. "We actually put jelly on the abdomen and just literally, slowly move the baby. We use ultrasound to see what position it's in."

External version worked for little Owen and he made his grand entrance into the world the natural way. For babies that remain breech, a C-section becomes the safest option for delivery.

Every day, more than 11-thousand American women give birth. Babies that are born early are more likely to be breech.
