Ladies thank you so much for your input.

I'm gonna go for it!

As you say, I can always hop out if I don't like it...but I can't imagine that I won't. DH is very supportive too - he said if I liked the shower in my last labour I'd probably love the bath (but he doesn't want to hop in!)

The obstetrician is a big fan of meeting the midwives so some of my appointments will be at the midwives clinic at the hospital - she says you get something from the midwives that you don't get from the doctor (and vice versa)...so I shall interrogate the middies about my goo (or, rather, poo) concerns .
