Dr. Katie Chetta joined host Bobbi Conner on Health Focus, MUSC’s health segment on South Carolina Public Radio, to talk about how breastfeeding boosts your baby’s immune system. The segment, “Breastfeeding boosts your baby’s immune system,” aired February 3, 2026.
Breastfeeding lowers a baby’s chance of being hospitalized for colds, pneumonia, or diarrhea. Dr. Chetta explains how antibodies, bioactive proteins, and milk cells help a baby’s immune system mature, and notes that milk responds when mother or baby is sick. Breastfeeding works best alongside vaccines and regular pediatric care.
