Well they're still suggesting it, or at least they were 6 years ago when my one and only was born!!!!
I asked my doc with my second boy about the benefits of a drink and he was evasive. My OB with my youngest ( she had a son the same age as my middle child and twin girls) said "Yes! But don't tell anyone I said so."
Ah, the duplicity that docs must engage in these days. ; )
