am with you there jen... just as our government have said that you shouldn't drink anything during pregnancy, NICE have come out and said that 1.5 units a day is ok...!!
for the life of me i'm not advocating drinking heavily - or even regularly - during pregnancy. i didn't drink at all from finding out i was pregnant right up until 14 weeks but i have had the odd small glass of wine or cava since. and i'm not going to feel bad about it, and don't think anyone else should as long as it is only a small infrequent amount.
personally i'm just as aware of all the other chemicals my body is absorbing on a daily basis and try to limit those too - there are a lot of ingredients in shampoo, deodourant, makeup, perfume etc that, although tested individually, have never been tested properly on humans in the combinations that we use and in the quantity that we absorb.
