With DD1 I couldn't drink any wine at all - I loved sniffing it but it was like acid if I put it in my mouth. However, I craved Guinness. My OB said I could have one a week and that should help with the craving but not do any damage. DD1 is a bright normal child.

With DD2 I didn't want beer but did want the occasional glass of wine which I also had. I agree with MN - read the studies and determine what course of action you will take. It's up to you to weigh up the risks and what you are prepared to do with your child. FWIW I think driving a car while pregnant carries more risk than one glass of wine but most people wouldn't give it a second thought.
