This will be my third child, second homebirth. We're using a different care provider this time due to insurance stuff. I'm sad that our last midwife won't be here for this birth (she doula-ed my oldest daughter's birth, so she's been there for both of my previous labors) but I really love the midwife team we're working with this time.
Because there's a whole team (two midwives and possibly an apprentice as well) attending the birth, I don't think we're going to use a doula this time. All the midwives are trained doulas as well, all are women I'd have felt comfortable hiring for doula work, and there should be enough of them there to support me as well as taking care of the medical stuff. If money weren't tight, I'd probably have my previous midwife there as a doula this time just because I would love for her to be there for all three of my children's births, but unless we have some sort of windfall between now and November I just can't justify the cost.
My advice to anyone feeling concerned about others' reactions is to go with the don't-ask-don't-tell approach. Most people won't even consider the possibility that you'll be delivering anywhere but the hospital, so you won't have to tell many people unless you want to. Tell them once the baby is here and safe - then they won't have anything to worry about.
My oldest sister spent my last pregnancy praying that I'd get preeclampsia so that I'd have to deliver in a hospital. (In her defense, she had a horrible birth experience with her oldest and honestly believes that she owes her life and possibly her son's to medical intervention.) She was scared half to death. No amount of data would convince her that this was a safe choice. I wish I'd not told her until after the birth - it would have saved her a lot of stress.
That said, I get a kick out of people's reactions, so I end up telling everyone about the homebirth plans, how great my midwives are, how much I loved my last homebirth, etc. It's a bit perverse, I know. But on the other hand, a surprising number of people have reacted positively, and I think I've even influenced a few women to consider homebirths. Granted most think I'm nuts, but that's not new.
