Hi B.,
I am currently seeing Ann Crowell (midwife) in Hurst. Though I don't know of someone in FW who is naturally oriented (doesn't mean they don't exist), I bet you could find a referral through Gene Sala (Inana Birthing Center, Denton), Ann Crowell (Gentle Beginnigs, Hurst) or one of several other midwifery centers in DFW. They all have back-up doctors for emergencies. I imagine one of them can give you the 'inside scoop' on an OB who would be willing to accomodate your needs.
My second recommendation would be to also look at the hospitals & their policies. Sometimes you can work backwards. That is to say, find a hospital with progressive policies and then look through the OBs who deliver there. 12 years ago, I delivered my son at a major hospital in San Antonio. Even back then, they allowed a bunch of family (grandmothers, SIL, husband, etc.) in the room during the delivery & I was able to get up & walk around quite a bit during labor. They also accomodated my request to room-in with my baby 99% of the time & they agreed not to give him sugar water. Had I known as much as I do now about natural childbirth, I would have pushed for more. I had an opportuntiy early on to tour the facilities and ask extensive questions about their policies. Any good hospital should be willing to do that for you.
One last thing: Have you checked out the midwive's clinic that delivers at Harris Methodist? Since they work so closely with doctors & the hospital there, I'm wondering if your insurance might bill them differently. It's worth a try anyway.
Hope all works out for you & kudos for going after what you believe is best for your baby!
B.
