Alcohol does cross into breastmilk and mimics the levels in the mother’s bloodstream (1) In the first month of life babies detoxify alcohol at approximately half the rate of an adult. (2)
Alcohol peaks in the breastmilk about 30 to 60 minutes after drinking it on an empty stomach or 60-to 90 minutes when taken with food. (2)
Occasional use of alcohol (one or fewer drinks per day) has not been found to be harmful to the nursing baby. (1)(3) Consider, if you do consume alcohol, one glass of wine, or one beer, to then wait approximately 2 hours before nursing again. One way to minimize the amount of alcohol your baby will get in breastmilk is to have the alcohol right after breastfeeding, so the least amount will be present in the breastmilk at the next feeding.
Pumping breastmilk does not increase the speed at which the alcohol is eliminated from the milk or from the body (1)
