Male Speaker: During childbirth the baby lies in the mother's uterus with his head pointing down towards the cervix, the first stages of labor begin with short regular contractions of the uterus every few minutes which continue until the mother's cervix is fully dilated, in the second stage of labor the contractions become more forceful, more frequent and more painful. As the babies head starts to move down the vagina, the amniotic sac breaks and fluid is released, the top of the head appears at the entrance of the vagina and finally bulges out. This is the crowning of the head. The contractions which follow push the baby even forward down so that the head is delivered the babies eyes immediately begin to blink and the mouth makes sucking movements the baby usually emerges facing the mothers back so that the head passes through the widest possible opening in the pelvic curdle. The head then turns that the upper end and the lower shoulder follows, there is a final contraction and the baby slips out still attached to the umbilical cord. The cord is then tied and cut, a painless operation because the cord is nerveless, the third stage of labor in which the placenta or after birth is delivered, is usually complete about 15 minutes after the birth.
