This study is building a large collection—called a biorepository—of breast milk samples and health information from breastfeeding mothers. Researchers will use these samples and information to study how breast milk protects babies' health, and how factors like or use during breastfeeding might affect babies' development and wellbeing.
Scientists want to better understand all the ways breast milk helps babies stay healthy and develop well. By studying samples from many mothers, researchers hope to discover how breast milk prevents or helps treat childhood health problems, and how maternal health conditions or treatments affect babies through breastfeeding.

If you join, you'll be asked to donate a milk sample (as much or as little as you're comfortable giving—from 2 ounces down to one teaspoon), answer questions about your health and family history, and complete short online questionnaires about your diet and how you've been feeling (about 30 minutes total). Your milk sample and health information will be stored long-term in the biorepository, where approved researchers can study them to learn more about breast milk and infant health.
