- Levels of alcohol in milk closely parallel maternal blood alcohol concentrations.
- It is not necessary to pump and dump milk after consuming alcohol, but expressing milk can maintain supply and avoid complications of engorgement if a feeding is being delayed.
- Alcohol inhibits oxytocin and can diminish milk supply.
- Even small amounts of alcohol in human milk have been shown to disrupt and shorten total duration of infant sleep.
- If a lactating person chooses to consume alcohol, exposure to the infant can be minimized by pumping or feeding just prior to drinking, limiting intake to 1 standard drink, and waiting at least 2 to 3 hours before directly feeding the infant again.
