Re: Thinking about changing dr/midwife
I switched OBs around 7 months with DS #1 and switched from an OB to a midwife at about 7 months with DS #2. No biggie. I think they do a global fee for pregnancy/delivery, so they just break it up by trimester or something. Check with your insurance.
I would try to stay with that group of midwives where you can get your waterbirth. Maybe just talk to the director about your concerns with the one MW.
