Can I breastfeed my baby if I have the flu?
CDC guidance says flu isn’t transmitted through breast milk. Learn how parents can reduce exposure and when to contact a doctor about treatment or feeding.
The short answer
CDC guidance says flu isn’t transmitted through breast milk. Parents with flu can usually continue breastfeeding or provide expressed milk while taking precautions to reduce exposure. If you’re within two weeks after birth and have suspected or confirmed flu, contact a healthcare professional promptly about treatment.
Breast milk can still be provided
The CDC says flu isn’t transmitted through breast milk. Flu spreads mainly from person to person through respiratory droplets, so it recommends continuing to provide breast milk while taking precautions to reduce exposure.
If you feel well enough, you can usually continue breastfeeding. If you’re too unwell or separated from your baby, the CDC says to express milk regularly if you can. If possible, a healthy caregiver who doesn’t have flu can feed the expressed milk.
Take extra care with a newborn
Newborns infected with influenza have an increased risk of severe complications. Take precautions whether you breastfeed directly or offer expressed milk. Wash your hands with soap and water before touching your baby or anything used during a feed.
A mask can also help reduce the spread of respiratory viruses. If you express milk, wash your hands first and follow current CDC pump cleaning instructions and the directions for your pump model.
If you need help with feeding
If you’re within two weeks after giving birth and have suspected or confirmed flu, contact a healthcare professional promptly. The CDC says people in this postpartum period are at higher risk and recommends antiviral treatment. A doctor can discuss treatment that fits your situation while breastfeeding.
The CDC says milk supply may decrease for some parents while they are ill. A lactation support provider can help with supply concerns. If you’re worried about your baby’s symptoms or can’t feed or express as usual, contact your care team.
