M.P.
O'Douls isn't a truly non-alcoholic beer. If you read the label, it has a really low level of alcohol in it. I know this because I used to be a bartender and I couldn't serve non-alcoholic beer to minors because it does have some alcohol in it.
I know that there are some women who drink wine or beer (occasionally & only one) while they are pregnant, but since there isn't any scientific proof about how much alcohol it takes to cause fetal alcohol syndrome, I would suggest just steering clear of anything like that all together.
