Homemama, definitely consider the move, especially since it's only 2 years. Consider it an adventure. You will learn so much. We moved from the center of the 4th largest city in the US - Houston - to this tiny town in Arkansas and have discovered so much more about what we as a couple like and don't like, need and don't need, in our lives. Our knowledge base about living conditions in different parts of the US will serve us well in deciding what will be best for us as a family in the long run, and where we want to live long-term. Have enjoyed making new friends and experiencing different weather and food. I'd say do consider going for it. You only get one life, might as well cram as much into it as you can.
Definitely standard here to be delivered by a doctor, and seen by one during pg. Many practicing OB/GYNs are women, though.
The midwife phenomena is new to the general population, & in many locations not well-integrated into the healthcare system. And it's extremely important that one's particular insurance company cover one's healthcare provider (and even so, for birth of DS1 we spent $1000+ pounds) - in many areas mw's just aren't covered.
Also, many patients don't trust yet that US mw's are as well-trained as US Dr.s, or that they will receive the same level of care under a mw.
As well, patients may think they'll have less choices, be forced into doing things more "naturally" with a mw - no epidural, for example, which for most US women is unthinkable.
Re: mw's as RNs: it's the same as in Britain, I think: some are, and some have gotten the stand-alone degree.
I was ideally looking for a young, female doctor here in Arkansas with whose personality mine clicked. I had that in Houston ... but here the only Dr. I found who would see me through to delivery without "rotating call" is a man. A sensitive, professional, softspoken male Dr. ... but still. At least it's my 2nd, and I feel like I know more what I'm doing.
Feel free to ask whatever you'd like; I never mind answering re: differences.
