Birth plans are most useful when you educate, inform and reinforce the birth plan with good choices. If you want a normal, natural birth, stats say your worst choices are private Ob, private hospital. Find a doula (50% less c/s, 30% less forceps, vaccum etc) and get some good birth education. The Pink Kit, the Thinking Woman's Guide to a Better Birth, Ina Mays Guide to Childbirth... anything on the BB recommended reading list.
