Wow - If i knew that there were actually Obs like that around I would consider recommending them!! How unreal for you to have the best of both worlds like that - I say go for it. Especially if you laboured drug-free first time around. I'm going to a birth centre where they have a 'labour pool' - as you are only permitted to labour, but not birth in it. The midwives at the centre are petitioning to have this rule changed.
If you don't like the pool you can jump out - but at least if you try it you will know why everyone raves about them!! Lucky you.

Goodluck!!
