There was a good thread about this on another due date group - can't remember which month. Lots of good information.
Anyway, my general feeling is that we are all victims of the obstetrical attempt to make pregnancy such a "delicate condition" that requires major medical care and lots and lots of overly cautious behavior (no soft cheeses, no alcohol, etc, etc, etc). I am NOT an advocate of "drinking while pregnant," but I think that an occasional glass of wine or beer with dinner is perfectly fine. And certainly I think that non-alcholic beer or wine is fine. If you look at other cultures and/or earlier times, you'll find that women were and are trusted to make good judgements about their babies and their bodies without the fear and guilt tactics employed here.
