I would like to know as well. I was offered a drink at my aunts the other night. My hormones were going out of whack, so I wanted one to chill out. But I didn't want to harm my son. So I didn't have one.
I was curious because a childless man on my FB went into rant about seeing a mommy in a restaurant breast feeding and having a beer. I saw no problem with this since it doesn't hit your milk instantly and one beer over a meal won't hurt. The post got my back up, he even commented to the mom if the baby was going to go for a smoke afterwards! The guy is an ignorant douche!!
