Vaginal birth - series—Procedure, part 4

Procedure, part 4

Overview

When your cervix is fully dilated, your doctor gives you the OK to push. Propelled by your effort and the force of your contractions, the baby makes his way through the birth canal. The fontanels -- soft spots -- on his head allow it to mold to the shape of this narrow passage. Your baby's head "crowns" when the widest part of it is at the vaginal opening.
