Understanding Alcohol in Breast Milk: What New Moms Need to Know
By Chris Colón, Certified Genetic Counselor at MotherToBaby Arizona
During pregnancy, many women make lifestyle changes to ensure the best possible outcome for their baby. After giving birth, some new moms consider reintroducing things they avoided, such as alcohol. But is it safe to drink alcohol while breastfeeding? In recognition of September’s Fetal Alcohol Spectrum Disorders (FASD) Awareness month, let’s explore the effects of alcohol in breast milk.
What Research Reveals
Studies confirm that alcohol can pass into breast milk, with concentrations similar to those in the mother’s bloodstream. Contrary to popular belief, pumping and discarding breast milk does not eliminate alcohol from it. The only way to ensure alcohol-free breast milk is to allow time for the body to metabolize it. It typically takes 2 to 2.5 hours for one standard drink to clear from breast milk. Each additional drink extends this time by another 2 to 2.5 hours.
Debunking Common Myths
There’s a misconception that drinking alcohol while breastfeeding can boost milk production. While beer was once thought to increase prolactin levels (a hormone linked to milk production), alcohol actually reduces oxytocin levels, which can decrease milk release. This may result in the baby receiving less milk.
Potential Effects on Babies
The impact of alcohol on infants through breast milk is not well-documented. Some studies suggest that alcohol exposure might affect a baby’s feeding and sleep patterns. While one study indicated possible motor development issues, others have not corroborated these findings. Factors like genetic differences and alcohol metabolism can influence how alcohol affects a baby, making the risk variable even among siblings.
Making Informed Decisions
If you consume alcohol, you might not need to cease breastfeeding entirely. It’s crucial to consult with your healthcare provider and your baby’s pediatrician to discuss your alcohol consumption and breastfeeding options. For personalized advice, contact a MotherToBaby counselor at (866) 626-6847.
