Also ask about labour -
What do they consider "too slow" so would consider you for drugs/C-Section?
Do they perform routine episotomies?
Are the drugs "on tap" or do they have to be brought in?
How much privacy do you get during/after the birth (ie do you have to share a loo, will students be around, when are you popped back on the ward with other people...)?
Will there be someone around to watch the baby if you need a shower the next morning if husbands are sent away?
What's the food like and do they have a fridge/microwave for snacks?
When do you go in: as soon as labour starts or give it a few hours until XYZ happens?
What would they consider an emergency or a need for induction/forceps/C-section?

You'll probably think of lots of questions when you're having a chat with the midwife anyway, but those were the sorts of questions I wanted answering. Quite often they know the usual questions so answer them without being asked! (Like the food and shower ones for me.)
