Key takeaways: Children under 5, especially under 2, are at higher risk of serious flu complications. The flu vaccine is recommended starting at 6 months. Babies under 6 months are protected by flu vaccination during pregnancy, breastfeeding, and vaccinated caregivers. Antiviral medicine works best when started early. Breathing trouble or dehydration needs urgent care.
Influenza can be serious for babies. Here’s how to protect your baby and spot warning signs.
Signs of Flu in Babies
- Fever, sometimes high.
- Cough and congestion.
- Fussiness or unusual sleepiness.
- Poor feeding.
- Vomiting or diarrhea.
Babies may not show classic symptoms. Young babies may have fever with few other signs.
Treatment
- Antiviral medicine (oseltamivir, sold as Tamiflu) is recommended for children under 2 with suspected or confirmed flu, even if otherwise healthy. It works best when started within 48 hours, but can still help later.
- Fluids and rest.
- Fever relief as advised by your doctor.
Prevention
- Flu vaccine during pregnancy protects you and passes antibodies to your baby.
- Flu vaccine for babies starting at 6 months. Children getting the vaccine for the first time need 2 doses at least 4 weeks apart.
- Breastfeeding may provide some protection.
- Vaccinated household members and caregivers.
- Handwashing and avoiding sick contacts.
Warning Signs
According to the CDC, seek medical care right away for:
- Fast breathing or trouble breathing.
- Bluish lips or face.
- Ribs pulling in with each breath.
- Chest pain (in older children).
- Not alert or interacting when awake.
- Seizures.
- Fever of 104°F or higher, or any fever in a baby under 12 weeks.
- Not urinating or other signs of dehydration.
- Symptoms that improve, then return or worsen.
Call 911 for severe breathing trouble, a seizure, or a baby who is unresponsive.
The Bottom Line
Flu can be serious for babies. Vaccinate during pregnancy, vaccinate your baby at 6 months and older, and seek care early.
