I've posted before that I had a home water birth with my first, and it was a wonderful experience. I'm happy to talk about it in more detail if anyone has questions. Obviously it's not something I'd be able to do this time, with twins.
Not to make a big issue of it, but comments to those who have had/are planning home births that it's somehow not safe are both incorrect and offensive. Most medical issues that would cause problems during a home birth would be picked up beforehand and you wouldn't be permitted to attempt one. If you have a low-risk pregnancy and live reasonably close to a hospital, there is generally no reason why it wouldn't be safe (that being said, I wouldn't attempt it if I lived, say, 40 minutes from the hospital. As it was, I knew if I needed to transfer, I would be there in 10 minutes). In fact, I think I had greater one-on-one attention than I would have in hospital; in fact for the last couple of hours I had the undivided attention of two midwives and a student midwife.
I found this website really helpful when considering my home birth: www.homebirth.org.uk. In particular, the 'But what if...' section helped me understand what would happen in specific medical situations.
I think there are just two types of people; those who feel safer being in hospital, and those who feel more comfortable labouring/giving birth in their own home. But that doesn't mean that those in the latter category are doing something unsafe, and it's unhelpful (and as I said, can come across as offensive) to suggest that.
