The entrance into the external environment of a neonate.
Act of being born; emergence of the fetus from the uterus, its separation from the mother, and the start of its independent life (usually after about 266 days of gestation); also called parturition.
The process in which a baby is delivered from the mother. In an uncomplicated vaginal delivery, the baby is pushed out of the uterus and through the vaginal passage known as the birth canal by involuntary contractions. Usually, the baby is delivered head first, but sometimes babies are born buttocks first (breech delivery) or feet first (footling breech delivery). Under certain conditions, the doctor may perform a surgical operation called a cesarean section (or C-section), in which the baby is delivered through an incision in the mother’s abdomen. A cesarean section may be needed when the baby is in a breech presentation or in serious distress; the labor is not progressing or is abnormally long; there is a dangerous infection; the birth canal is not large enough for the baby’s passage; or in another situation in which a cesarean is thought to be safer for the mother or baby.
The act of being born; passage of a child from the uterus.
