Thanks again all, especially all the good wishes.
puppypower – congrats on your new arrival. Don't worry, I don't consider the whole too posh to push thing to be reaqlistic or accurate. Mrs N was facing a high chance of a section anyway, so the fact the baby is "footling" breech (seems to be the worst kind) means that she's booked in. She's nervous, but it solves other worries.
Pics, gender and a name to follow at the end of the week.
PS I do intend to get Mrs North something, though certainly not through any sense of obligation – it's because I love her.
