Avoid products with alcohol, as it can pass directly into breast milk and affect your baby’s development. If you’re unsure, check the label for active ingredients and compare them to trusted lists from the American Academy of Pediatrics or LactMed. Always talk to your pharmacist—they know which formulations are safest and can often recommend alternatives that work just as well without the risk.
