Did she ever have her pregnancy confirmed? When I have had my pregnancies confirmed, that is when I get told to take folate, not to drink or smoke (not that I do anyway) and I get my BP and everything else checked. I am suprised that she was so uneducated on pregnancy care. Fair enough not knowing about folate, but it has been a known fact for a very long time that drinking isn't good for your baby. I remember knowing that when I was a child.
I hope from now on, the woman you work with reads up on her pregnancy and asks alot of questions at all her appts.
