Is it ok to drink alcohol while breastfeeding?

Yes: Small amounts of alcohol are okay while breastfeeding. A glass of wine or few sips of beer can even help with breast milk letdown. Drinking to excess while breast feeding is not in anybody's best interest. The alcohol can change the flavor of the breast milk, however.

Yes: Light drinking, generally less than 2 drinks per day, is allowed. However, moderate drinking causes irritability or excessive sleepiness, weak suckling in breast-fed infants, and decreases milk supply. Breast feeding should be avoided during and for 2-3 hours after moderate drinking. Chronic or heavy drinkers should not breastfeed.

No: If we do not drink when we are pregnant, why would we want to when we nurse? The ammount that passes through breast milk is proportionate to the ammount ingested, so it depends on how much you weigh, how much you drink, what kind of drink, concentration of alcohol, and how long after you ingest alcohol you nurse.
