My first DS was a home waterbirth, attended by MW. I intend to do the same for this one. Initially, I had planned to give birth at my MW's birthcenter, but as the time came nearer, the idea of getting in a car and driving to the birthcenter seemed very disruptive, and it seemed much more comfortable to just be at home. So we altered our plan. I also did concurrent care with an OB (who did not know that I was also seeing a MW). He wanted to induce me 3 weeks early because I'm overweight and he was of the opinion that that put me at risk for a large baby I couldn't birth (very stupid, and rather unsupported "fear" that OBs tend to hold, and not something he ever told me but that I've researched recently and figured out on my own). Needless to say, my DS was 7 lb 14 ou - a very normal, average weight for a newborn.
I also wanted to mention to those of you who are chosing the OB/hospital path, that I highly recommend hiring a doula. Especially if you intend a non/low intervention birth or natural birth. I am considering hiring one myself, even though I'll have MWs. (Not all MWs are present for your entire labor, depending on the practice. A question to ask when you're interviewing MWs.)
