All About Breastmilk

Part of our COVID-19 & Breastfeeding: What You Need To Know Series

Written by Heather Bingham, IBCLC and Jennifer B. Greenberg, M.Ed., IBCLC

Breast milk provides protection against many illnesses, including respiratory illnesses like COVID-19. We haven’t had much time to study the new coronavirus and breastfeeding, but we do know that rates of transmission of respiratory viruses through breastmilk are typically low. Because of this, the World Health Organization states that mothers with COVID-19 can breastfeed.

Important takeaways: 

  • Breastfeeding likely provides protection for babies from COVID-19
  • The World Health Organization states that mothers with COVID-19 can breastfeed
  • In limited studies on women with COVID-19, the virus has not been detected in breast milk
  • We do not know for sure whether COVID-19 can be transmitted via breast milk

If the infection is diagnosed or suspected, the CDC recommends precautions to avoid spreading the virus:

  • Wash hands before feeding.
  • Wear a mask while feeding if you are choosing to directly breastfeed.
  • If you choose to express breast milk, use a dedicated (unshared) pump.
  • Wash hands before touching any pump parts or bottles.
  • Follow recommendations for proper pump cleaning.
  • Consider having someone else, who does not have COVID-19 bottle feed the baby.

Be sure to discuss your feeding decisions with your doctors.
