Tallulah hope it goes well at the office, dont let your boss pressure you though and to the moaning biddy who doesnt like babies, can you pick out a defining feature of hers and bemoan it for the next 5/6 months, like "Ohh I HATE it when people cant be bothered to brush their teeth and then breath all over you at the coffee machine" or similar?? 
angels good guess it was indeed polhill!
Am REALLY swaying towards the 'fiding out boy or girl' now, dont want to be the only one who doesnt know! The CPC says boy and I am convinced its a boys as we only seem to do blue versions in my family (3 sisters, all with 2 boys each) but will see how we feel on the day.
Am not doing antenatal classes this time round no as dont know if I would have the time but first time round did the NCT classes and still great friends with 5 of them (2 fell off the radar) although I think we were very lucky to ALL get on so well. Have bigged up the classes to everyone I know and then they always say how it didnt quite live up to their expectations. The dads all get on well too and still go out for beers.
I did find them useful though because the NCT give you a slightly different persepective to the birth than the hospital classes - they advise you about what options are available to you so that when in hospital, you dont just have to go along with what the docs/midwifes say unless you are happy to e.g My doc told my MW to give me pethadine when I wasnt even in that much pain - she didnt ask me or even look at me, and I piped up with 'No thanks I'm fine' yet I would normally have just gone along with whatever the doc said (and dont normally confront anyone) She just looked at me and shrugged.
Dont get me wrong, 4 hours later I was begging for en epidural but still! Just felt the NCT helped me get my own idea of what I wanted, rather than what the doc told me had to happen.
They do push the b'feeding though (which was fine as I wanted to but the woman that came to one class to do a talk was a Nazi, I swear, and I was on her side!)
