I've heard of that too..Someone suggested it to me when they found out i was pregnant. But i don't drink that much to start [maybe a drink on a special occasion]
So i didn't think that i should pick up this 'one glass of wine a day' thing, when im not a drinker really. I don't really think a glass of wine a day is a good idea anyways..but i guess some choose a different path.
I just dont see why anyone would drink after seeing a positive sign on a pregnancy test...
Hopefully she did not drink very much, because the first 3 months are very important.
