I have now had 2 FBC experiences. Well, strictly speaking, it was only one, as DS was born at home as he came way too quickly (birth story in my siggie).
We are only planning on the two kids that we have, but if, for some reason, I will face the decision of where to birth again, then I will definitely plan for a HB.
My reason:
I don't want to labour the whole time in the hospital as I don't want to be "on the clock". But both my labours had one thing in common: things picked up very suddenly, rather than a steady incline. And with my last labour, once things got serious, there was no way I could have gotten to hospital in time. The next labour could be even quicker. DS was an unplanned HB with only me, DD and my mum there. Things went really well, and I will treasure this experience forever. However, I think it is much safer to have a planned HB with an experienced MW, than a freebirth. So, this is why I would choose a HB next time, so i won't be in the situation again where I will have to give birth unassisted (this terminology is unfair to my mother who was a great support).
