Thank you for all the positive replies. Elsa09, I hadn't thought of asking the private midwife team at the actual hospital, so good suggestion.
Curly, did you also use the neighbourhood midwives? To be fair to St Thomas's, a possibly with your friend, they are reiterating that there just will not be a repeat of last time, but I guess my faith is somewhat dented. However, good to hear they did actually see that through for your friend.
Out of interest if there is an extra person in attendance, do father's end up being a bit pushed out, or is it a matter of everyone has their role as such? Not that my other half would probably mind if he was jobless after last time, which he describes as the worst 36 hours of his life!
