Should I breastfeed?

Short Answer

If you have a mild case of seasonal flu and are otherwise healthy, continuing to breastfeed is generally safe and can provide your infant with protective antibodies. However, if you have a high fever, severe respiratory symptoms, or are taking medications that are not compatible with breastfeeding, you should pause feeding and consult a healthcare professional. Good hand‑washing, mask use, and staying hydrated are essential regardless of the decision.

When It Makes Sense

• Good fit: You have a low‑grade fever, mild cough, and no complications; you are able to practice strict hygiene (mask, hand washing) and are not on restricted medication.
• Good fit: Your infant is less than six months old, when passive immunity from breast milk is especially valuable, and you have access to medical advice confirming safe medication use.

When You Should Avoid It

• Warning sign: You are experiencing a high fever (> 102°F/38.9°C), severe fatigue, or vomiting that makes it difficult to nurse safely.
• Warning sign: You are prescribed antiviral drugs or other medications that have known breastfeeding contraindications, or you have a chronic condition that worsens with flu infection.

Pros and Cons

Pros

• Breast milk contains antibodies (IgA) that can reduce the severity of flu in the infant and support their developing immune system.
• Maintaining lactation prevents supply reduction, which can avoid painful engorgement and the need for later pumping or formula supplementation.

Cons

• Close contact increases the risk of transmitting the virus to the baby, especially if hygiene measures are imperfect.
• Some flu treatments (e.g., certain antivirals) may be contraindicated for breastfeeding, requiring temporary cessation or formula supplementation.

Decision Checklist

• Is your fever low and manageable, and can you maintain proper hand hygiene and mask use while nursing?
• Are any prescribed medications compatible with breastfeeding, according to your healthcare provider?
• Do you have a backup feeding plan (expressed milk, formula) in case you need to pause direct nursing?

Alternatives to Consider

If you need to limit direct contact, you can express breast milk and have a healthy caregiver feed the infant using a clean bottle. This preserves the immunological benefits while reducing viral exposure. In cases of severe illness, temporary formula feeding may be appropriate, followed by a gradual return to breastfeeding once symptoms resolve.

Final Recommendation

For most mothers with mild flu symptoms, continuing to breastfeed—while wearing a mask, washing hands frequently, and confirming medication safety—offers more benefit than risk. If you have a high fever, severe respiratory distress, or are on restricted medication, pause direct nursing, use expressed milk or formula, and seek guidance from a qualified health professional. Always prioritize both your recovery and your infant’s safety.
