Very interesting to read Sloane about the study and I think is great that you are participating - as the 'no alcohol' thing from what I have read is all about the fact there have not been any studies done on the impact of very low levels of alcohol during pregnancy so it is easier to say not to have any at all (is like a lot of drugs/pharmacy products etc there hasn't been enough studies to say it is safe to have so they just state not to be used during pregnancy).

I have had the odd half glass of wine or odd half a beer (so half a pot/midi etc) during both pregnancies, and do the same now breastfeeding (so maybe once a week but did depend on stage of pregnancy - e.g. I probably didn't have any in first tri and more likely to have had the odd drink towards the end - with breastfeeding probably didn't have any in first 6 weeks or so, and now if have one will be when I have a big gap in feeds). As there is no real research on low levels of drinking my personal choice is based on the anecdotal evidence surrounding me where people have drunk in very low levels during pregnancy and the fact I acknowledge there is a level of risk with everything we do and judge what is my own acceptable risk level. I pretty much apply the "a little bit of what you fancy always does you good" rule to most things.
