I had a glass of Moet on my 30th when I was pregnant with DD. I was more than comfortable with my choice to do so (as was DH) and that's what's important if you choose to have a drink - that you are OK with your decision

I didn't like the smell or taste of wine while PG with DD (champers being the exception) which was so strange for a girl who loves her wine! Red wine smelt and tasted like paint stripper White wasn't much better so it was easy for me to avoid them.

This pregnancy is different though. White wine smells appealing and I've had a couple of tiny sips of red and it tastes normal I'll continue to avoid it though as I'm surprised at how easily I can avoid it (keeping in mind I love my wine normally!) but I'll allow myself to have a small glass at special occasions, like my friend's wedding in September.

Some of my friends current OBs are saying a couple of wines a week is fine, some are saying no alcohol at all. Like a PP said, the lack of knowledge on how much (or how little) alcohol is 'too' much is why the 'rule' tends to be 'no alcohol at all'. But as long as you're comfortable BAL then really that is all that matters.
