Researchers are still learning if COVID-19 can pass through breast milk and cause infection in the baby. Most information shows that it is safe to feed breast milk to your baby when you have COVID-19. Remember that breast milk is the best source of nutrition for most babies. Breast milk also helps protect babies from infections, including infections of the ears, lungs, and digestive system. For these reasons, having COVID-19 should not stop you from giving your baby breast milk.
