Love, love, love Ina May Gaskin. Her approach is so reasonable:
"It's very rare to see an undisturbed birth in a modern U.S. teaching hospital, but when you see a woman who isn't frightened, who's giving birth without interference, you stand back in awe and realize how little needed you are except in the rare circumstance. That doesn't mean that you shouldn't be around in case there is a problem. It just means that you should be able to tell when there's a problem, and you should be able to tell how not to create problems."
