Don't be absurd. Midwives are practitioners in the field of child birth. Some will have acquired a highly developed sense of what works and what doesn't. It is foolish to ignore their experience.
My wife's cousin is going through the program right now and will graduate with the equivalent of an MD. She's doing residency at a large hospital in Seattle and did clinical at another in Boise. When she graduates she'll be working adjunct at either another hospital up here, or through Stanford. I'm no medical expert, but I trust her experience and expertise. I'm not sure where you're information is coming from, but I think you may be misinformed.

I think you're thinking of midwives from a few hundred (or more) years ago, before the fields of medicine and nursing existed as they do today.
