Drinking excessively, can be very dangerous to your baby if you are breastfeeding as a young baby under three months old does not have a mature enough liver to process the alcohol. To have an occasional alcoholic drink has not been proven to do any harm. So if you would like to have a glass of wine or something similar during the holiday season, go ahead. But, remember pumping and dumping, or drinking alot of water will not remove the alcohol from your blood stream. You simply need to give the alcohol time to work it’s way out of your bloodstream and breastmilk. So for as long as you feel the effects of the alcohol it will be in your breastmilk and you should not be feeding your baby at this time.
So enjoy a little, but make sure you have some reserve breastmilk, while your body’s metabolism has time to digest the alcohol. Enjoy in moderation!
