You don't need to swear off booze

Although when you're pregnant you need to steer clear of any alcohol, it's fine to have a glass of wine or beer a few hours before nursing, says Dr. Wilwerding. "If you drink more than that, 'pump and dump,'" she says. Still, be careful not to overindulge: Two or more drinks per day may harm your baby's motor development and may interfere with your "let-down," the reflex that allows milk to move from your glands to your nipples. (You'll be in a lot of pain if milk builds up in your glands.)
