Hi A.,
You can find ob/gyns in a hospital setting that are "open" to natural childbirth. The problem is, they don't know anything about it or how to actually accomplish it. Their idea of natural childbirth is to stand around and watch you try to give birth by yourself, using your own resources. If/when you begin to falter (because after all you've never done it before and you have no guidance), they will ride in on their white horses and "save the day" with drugs or surgery. It never occurs to them, or the countless women that they do this to, that it was their lack of support that led to your difficulty in the first place.
When you are interviewing, ask them how many women in their practice ACTUALLY HAD a natural birth in the last five years. Or, what percentage of women who intend a natural birth actually end up with one? It is probably not that high. Having said that, a doula is a MUST in a hospital. Even then, natural birth in a hospital will not be impossible, but will be a challenge.
The better place to be is in a birth center. You can try Birth and Women's Center near Baylor Dallas or Allen Birthing Center in Allen. It's a much better bet. You can try a midwife with hospital privileges, but you still have all the hospital restrictions and they may not give the same high level support of a birth center. Women's Health Alliance at Baylor Dallas have a few midwives with hospital privileges. There is another practice in McKinney with a staff midwife - North Centeral Women's Health Partners, LP.
Good luck.
