Can't believe I read the whole of this - I don't usually have the patience...
I often hear people justifing their unsubstantiated fears (and their prejudices) with 'it's common sense, innit?' we all do it to communicate opinions that we can't, for whatever reason, back up with facts. It does irk me when it's applied blindly to issues like this.
'Common sense' tells me that thousands of generations of foetuses have been exposed to alcohol with no ill effects( eg, as mentioned earlier in the thread, in days of yore beer was drunk in preference to dodgy water; and I wouldn't be surprised to learn that devout pg women throughout christendom forced down a gobful of wine at communion each week, no matter how awful it tasted to them). 'Common sense' also tells me that a small glass or two of wine a week won't do any harm unless you are the lightest of lightweights and are capable of getting squiffy on that amount, or avoid it if it's just not agreeing with you.
All of you ladies that say that alcohol=bad is common sense, do you know personally of anyone who was adversly affected by their mother consuming light/moderate amounts of alcohol?
When I fell pregnant I didn't touch alcohol as I felt I had no use for it. I was indifferent to the stuff and, since I couldn't think of any nutritional value to my usual tipples, I kept my limited appetite for other 'worthwile' stuff that my body seemed to want. However once I reached my second trimester, I started to really really crave red wine, and only red wine, which I never used to drink pre pg, so 'common sense'told me to listen to my body and have a glass about once a week when the urge took me. Since my poor tum would quickly eject anything that it didn't want, even if it was a spoon too much food , I took this as a 'common sense'sign that the wine was actually doing me some good! And boy did it taste great to me . Strangely enough one glass was always enough and I never degenerated into a mindless lush, which I guess is what our wonderful, all-knowing, Blubberment believed would happen.
Of course, if I'd followed the 'common sense' premise that a large proportion of everyone who had ever been born had been damaged by small amounts of alcohol (it wouldn't be much of a risk if it didn't occur often enough for at least some people you know to know of someone affected), I would have spent my pg in a state of self loathing at my selfishness.
