Can I Breastfeed if I’m Sick?

Yes! In most cases, you should continue breastfeeding even when you are sick or have a fever. Your body makes antibodies (special protections) that pass through your milk to your baby. It’s like giving your baby a magical extra defense right when they need it most.

Tips if You’re Sick

Rest and Drink Fluids.

In most cases, you should continue breastfeeding even when you are sick or have a fever. Your body makes antibodies (special protections) that pass through your milk to your baby. It’s like giving your baby a magical extra defense right when they need it most.

Handwash
Wash your hands often.

Wearing a mask around your baby can also help prevent spreading germs.

Milk_Pump
If you feel too sick to nurse, pump your milk.

Have another caregiver feed your baby with your pumped milk so your supply stays strong.

Chronic_Illness

If You Have a Chronic Illness

Health conditions like asthma or diabetes can make you feel worse when you’re sick. It’s important to keep up with your care. Take your daily medicines as prescribed. Stopping them suddenly can make you feel worse and affect your milk supply.

Talk with your WIC provider and health care team about medicines or treatments to keep breastfeeding safely.

Medicines_bottleMedicines and Breastfeeding

Antibiotics:

  • ✓ Most are safe, but some may cause side effects, like giving your baby looser stools.

Cold remedies:

  • ✓ Vitamin C: Up to 120 mg is safe.
  • ✓ Zinc: 25–50 mg is safe and may help shorten colds.

Watch for MastitisWatch for Mastitis

If you have a fever, chills, body aches, or just feel “off,” it could be the start of a breast infection called mastitis.

Your breast may not look red or swollen at first, so pay attention to how you feel. If your symptoms get worse or do not improve after 24 hours, get medical attention right away.

Extra CarefulWhen to Be Extra Careful

Some illnesses need special care or treatment before you can safely breastfeed:

  • HIV: If your viral load is low and you are on treatment, your doctor may recommend breastfeeding.
  • Herpes or chickenpox (varicella) on the breast: Your baby can feed from the breast without sores.
  • Active tuberculosis: Wait until treatment makes you non-contagious (about 2 weeks).
  • Varicella right around birth: Baby may breastfeed if vaccinated.
  • Hepatitis C with bleeding nipples: Risk is higher when blood is present.
  • Ebola: Breastfeeding and close contact should be avoided. Ask others to help care for your baby until you are no longer contagious.
  • Zika virus: Some reports show it may spread through breast milk, but usually breastfeeding is still safe. The World Health Organization and CDC say the benefits of breastfeeding are greater than the small possible risk of passing the virus through milk. Talk with your health care provider to decide what’s best for you and your baby.
  • COVID-19: Moms with COVID-19 can keep breastfeeding. The virus does not pass through breast milk, and the antibodies in your milk actually help protect your baby. Wash your hands before touching your baby or pump parts, and wear a mask while feeding if you are coughing or sneezing.

In most cases, it is safe – and even good – for your baby if you keep breastfeeding while you are sick. If you’re unsure, talk with your health care provider or WIC staff. Remember to rest – your body needs time and care to recover and return to good health!
