Dutch advice is not a drop should pass your lips. Honestly the lectures I've had on it, would make you think it was heroine! I've just not told them if I've indulged!
When I was pg with DS it as a few units in a week was no problem, but at Christmas I read an article which said that guidance had changed to advising best not to drink at all, but maybe if you did only a unit or two.
I drank small amounts in both previous pregnancies but didn't feel I had to hide it. Here I very much feel I do, so haven't.
