All this talk of baby programmes, and here's me sitting here copying 'In the Womb' from Sky+ onto a video tape as I type! Diddle - was it 'Life Before Birth' that you have to watch? It was quite good, but had lots of very annoying poetry throughout! 'In the Womb' seems to be pretty much the same programme, but without the poetry, and with a bit more info I think (it was on National Geographihc a couple of weeks ago).
WC - I worried about whether flying had caused my m/c too, as I was actually on hols when it died, even though I didn't know it at the time. My midwife knew I was flying and said it was fine, but a GP friend who also had m/c after seeing heartbeat at 8 weeks reckons that there may be some risk, although hard to prove. I have chosen not to fly during this pregnancy, as even if it is totally unrelated, I, like you it seems, would forever wonder if things went wrong again.
I did give up alcohol, coffee etc whilst ttc again, and will be staying off them throughout pregnancy. I agree that a little whilst ttc shouldn't do any harm, but they all decrease fertility, and with the length of time it took for me to fall pg the first time, I just didn't want to do anything that could delay it happening again.
Xena - well done to DD2 you proud mummy!
