Vertex Position
By 36 weeks, most babies turn into a head-down or vertex position and remain there until birth. Most babies in the vertex position are face-down, but the head can also be sideways or face-up.
Breech Position
In 4 percent of births, the baby does not turn head-down but remains breech. Breech positions can be frank, with the buttocks first; complete, with knees bent and feet at buttocks; or footling, with one or both feet stretched straight out.
External Cephalic Version
If your doctor discovers your baby is breech before labor, he may attempt an external cephalic version, a method of trying to turn the fetus head-down by pressing on various areas of your abdomen.
Breech Delivery
Most babies that present in breech position are delivered via cesarean section due to the dangers of a vaginal delivery.
Other Positions
Sometimes babies can be lying completely sideways, called transverse position, or shoulder-first.
