I've only read the first page and the comments that stood out were - 'one glass can't hurt can it?
And 'the midwife said a glass of wine was ok with a full belly'
Actually we don't know what harm alcohol actually does on a glass to glass basis because we can't research it, we do know regular alcohol when pregnant can chase huge problems though. Just because there isn't evidence on occasional drinking doesn't mean its ok to do it.
What may affect one baby, mightn't another. It's known that alcohol kills developing brain cells, so if anything it's worse earlier on in pregnancy.
The last update we had on alcohol and advice was - don't drink at all. Then the specialist showed us a video - a baby in utero of a mum who hadn't anything to drink, and the comparison of a baby In utero who's mum had a few glasses of wine. This baby was making jerking movements. It wasn't nice to watch.
I think the problem is NICE guidance says you can have 1-2 units a week, this leads mums to believe its ok, when in fact we don't know its ok. I tell mums at booking the only way to guarantee your baby isn't affected by alcohol is to refrain. That said, their body their choice.
