Most medications are compatible with breastfeeding — the dose your baby gets through milk is typically a tiny fraction of the maternal dose. But “compatible” still requires checking. This section teaches the LactMed lookup workflow, walks through the most common questions (pain meds, antidepressants, birth control), and addresses the maternal-side topics that get overlooked: stress and supply, nutrition myths, breastfeeding with chronic infections. The goal is to keep mothers on their meds and well-fed — because a depleted, unmedicated mother is the bigger risk to the dyad.
