MODEL RELEASED. Newborn baby after Caesarean. Newborn baby resting after being delivered by Caesarean section. The white substance on the baby's skin (right) is known as vernix, which lubricates the passage through the birth canal in vaginal deliveries. During a Caesarean section, the baby is delivered through an incision made in its mother's abdomen and uterus. This procedure is performed when it is difficult or dangerous to deliver the baby in the normal way. Photographed at St. Mary's Hospital in Lacor, Gulu, Uganda.
