I must say I share welshie's scepticism about this, no-one is going to say "hurrah, a bottle a night is good for you during pregnancy" (would be nice if they did though) and let's face it, most of us would be deliquents if alcohol was always harmful even in small quantities, as our mums didn't know they weren't supposed to drink.
Equally my little (adopted) niece seems fine despite her birth mum having been p*ssed for the entire pregnancy. (Whilst not advocating that as a good strategy, I should add). Although it's too soon to tell if she will be a delinquent as she is only 2 1/2 She did try and pull her trousers down in the restaurant yesterday but I'm not sure that qualifies as deliquency.
I think the issue is that no-one knows what a safe amount is, and no-one can really do any research into it, so there's unlikely ever to be any definitive advice on the subject. Of course the safest option of all is not to drink anything at all, but within reasonable limits I think it's up to the mother to decide what risk she is prepared to take.
And on the final note before I come down off the soapbox, I will add that I think my niece was more damaged by her birth mother having been p*ssed the whole time after she was born (as well as before) - she wasn't fed properly and was very underweight when she came to my brother. It took a long time to encourage her back to eating (the foster parents had obviously fed her but didn't have time to devote to her appetite as they had loads of other kids in the house). She was terrified of loud noise and her little bro couldn't even smile at 6 months old. To me, excessive boozing in pregnancy is bad, but excessive boozing in charge of a baby is far worse.
Btw, on a completely different note, my bump seems to have expanded rapidly over the weekend, like KVG's. Very bizarre. Dh has taken to prodding my tummy to see if he can get the baby to kick, I am definitely not enjoying that!
