Breastfeeding helps protect your baby from the flu – even if you’re feeling unwell.
Breastfeeding is one of the best ways to help protect your baby from illnesses like the flu. Your breastmilk has antibodies and immune factors that support your baby’s health, even if you catch the flu yourself.
Can I still breastfeed?
Breastfeeding helps protect babies from a variety of illnesses, including influenza. This is because breastmilk contains antibodies and other immune protective factors. If you have been diagnosed with or are suspected of having influenza, you should take care to avoid spreading the virus to your baby while you continue to breastfeed. Influenza is not spread to babies via breastmilk. Rather, people infected with the flu can spread it to others via tiny germ droplets (eg when coughing or sneezing).
Can I keep breastfeeding if I have the flu?
Yes, you can keep breastfeeding. The flu virus isn’t passed to your baby through breastmilk. Instead, it spreads through droplets in the air when someone coughs or sneezes.
How can I help stop my baby from getting the flu?
- Wash your hands well with soap and water before touching your baby or anything your baby touches.
- Wash your hands after you sneeze, blow your nose, or cough.
- Try not to cough or sneeze near your baby.
What if I feel too unwell to breastfeed?
If you’re not feeling well, ask someone to bring your baby to you for feeds. You might find it easier to feed lying down or laying back with your baby on your chest. If you’re too unwell to breastfeed directly, you can express your milk so your baby still gets the benefits. Remember to wash your hands and clean all equipment properly.
What about my milk supply?
Some mums notice their milk supply drops a little when they’re unwell. If this happens, you can call an ABA counsellor for support and tips for building your supply.
