My midwife very wisely suggested I didn't give birth in my bedroom. I put the pool in the spare room and we could close the door on the pool and the wet towels and what have you and get into lovely clean sheets in my own bed. Midwives take away the "mess", but DH didn't have to worry about tidying up until he was ready because the bedroom was pristine.
Whatever you would do with the children when going to hospital, can be done with a homebirth. My 12yo DD slept through me giving birth though. DH woke her up at 6.30am to tell her her sister was born.
Can't recommend it highly enough, but if you're not comfortable with it, then it's not for you. It is worth considering, is all I'll say.
The only disadvantage for me, was that I'm a bit shy about phoning and "bothering" people, so when I could have done with some breastfeeding support, I was afraid to phone the on-call midwife to come back and help. I was being very silly, I should have just done it - it's their job after all. Also DH went out for a while (to sort out some work stuff) in the evening of the day she was born and I know now that I wouldn't let him do that again, because despite being able to cope just fine, I did feel a bit alone.
That said, you do hear lots of stories about women not getting any post-natal support in hospital even though they ask and being left alone without support...
