DD will be looked after by MIL at MILs house, who will be in which ever town/city we are living at the time.
I don't plan on a free birth. I just want to know what I need to know IF I were to have one as a result of staying at home for as long as possible, as I believe giving birth before arriving at hospital is a possibility when staying at home for as long as possible. I only intend on doing this because I want to be where I am most comfortable, rather than go to hospital and have my labour go backwards because I am uncomfortable and stressed, so will be labouring at home for as long as possible, which I believe a lot of women do.

I don't think I am being irresponsible and putting myself and my child at risk. I am having a uncomplaicated, text book pregnancy so far, and as long as everything is looking fine, I see no reason why I can not labour at home for as long as I feel necessary.
As for first aid courses, both DP and I have done them, and I have even done specifics in infant and child resusitation and first aid. I keep updated with my first aid and am more than comfortable with my ability to act in an emergency.
