Why Home Birth?
Many couples plan home births because they believe that most of the time pregnancy and childbirth are normal functions of a healthy body, not a potential life-and-death crisis that requires the supervision of a surgeon.
At home, you decide where to deliver, you can move around as you desire, decide who you want there. There is no risk of unnecessary interventions, you can eat your own food, cuddle in your own bed, have a waterbirth, have siblings there or not.
Birth in a hospital is a recent cultural phenomenon, not based on research.
