I think in our culture women (no thanks to the media) think that birth is an emergency. It's some kind of health problem. Childbirth is not a dangerous disease. It is a normal function of a woman's body. Yes complications can occur, but so can a car accident the next time you leave the house. Birth is normal. Natural birth is beautiful. Complications need to be medically managed. Birth in itself should not be.
