Wikipedia
Natural childbirth is childbirth without routine medical interventions, particularly anesthesia. Natural childbirth arose in opposition to the techno-medical model of childbirth that has recently gained popularity in industrialized societies. Natural childbirth attempts to minimize medical intervention, particularly the use of anesthetic medications and surgical interventions such as episiotomies, forceps and ventouse deliveries and caesarean sections. Natural childbirth may occur during a physician or midwife attended hospital birth, a midwife attended homebirth, or an unassisted birth. The term "natural childbirth" was coined by obstetrician Grantly Dick-Read upon publication of his book Natural Childbirth in the 1930s, which was followed by the 1942 Childbirth Without Fear.
