Childbirth (also called labor, birth, partus or parturition) is the culmination of a human pregnancy or gestation period with the birth of one or more newborn infants from a woman's uterus.
Childbirth could be achieved through normal (natural or vaginal) birth or through cesarean section (c-section).

The process of normal human childbirth is categorized in three stages of labour: the shortening and dilation of the cervix, descent and birth of the infant, and birth of the placenta.

Caesarean section is the removal of the neonate through a surgical incision in the abdomen, rather than through vaginal birth.

The videos below cover both natural delivery and cesarean birth of a baby.
