When the cervical tissue thins and the cervix becomes dilated to 10 centimeters, the expectant mother has reached the second stage of labor. It is time for the baby to be born. At this point, she may feel some burning near the perineum.
Most babies enter the pelvis with the head facing to one side. They then rotate to face downward, toward the small of the mother’s back. Delivery presentation is the baby’s position as it comes down the birth canal.
About 97% of babies are in the cephalic, or head-down position, the optimal position for childbirth.
