Alcohol and breastfeeding: What new mothers need to know

Moderate alcohol use during breastfeeding is common but carries considerations that mothers should understand.

What happens

Alcohol passes into breast milk at approximately blood alcohol concentration. Peak milk alcohol level occurs 30-60 minutes after drinking. A single drink produces relatively low levels in milk.

The pump-and-dump myth

Pumping and discarding milk does not speed alcohol clearance. Alcohol leaves breast milk as it leaves the bloodstream, over time. Pumping is only useful to maintain supply and relieve engorgement, not to remove alcohol.

Guidelines

Wait 2+ hours after a single drink before nursing. Avoid nursing during peak blood alcohol. If you feel the effects, wait. Occasional moderate drinking (1-2 drinks) is generally considered compatible with breastfeeding by most medical organizations.
