Okay, replying to this:"They also strongly advise epidurals (which I don't want) and, I believe, prefer delivery to be in an operating theatre, which I cannot imagine!"
Obviously, it seems to differ from hospital to hospital, but I had my twins last year, and I didn't have an epidural. They were very willing for me to have one, but I didn't want one.
I was in a delivery room, fully dilated, waiting for second stage, when I began wanting to push.(I won't bore you with the details of the lead-up to stage 2!)
I called the midwives, and they wheeled my bed into the operating theatre, along the hallway. The midwife in charge of me turned most of the overhead lights off, so it stopped being so noticeably an operating theatre. Which was really nice of her. Then they helped me onto a operating table type affair, and adjusted the segments of the bed to my liking. The only bad part of the delivery bit was the narrowness of the theatre bed- kept feeling I would fall off, so dh and midwives had to hold on to me at the sides.
Then I pushed, and I got two babies.
Other things I learned to pass on to others: 35 weekers can breathe. Had convinced myself they would need to be on respirators, to the point of outright ignoring midwives who tried to reassure me!
