Nothing causes a new parent more panic than feeling their baby’s forehead and realizing it is unusually hot. While a fever can be scary, it is actually a sign that your baby’s immune system is doing its job and fighting off an infection.
However, how you handle a fever depends entirely on your baby’s age and symptoms. Here is a quick guide on what to do when your little one’s temperature rises.
The “Danger Zone”: Under 3 Months Old
If your baby is under 3 months (90 days) old and has a rectal temperature of 100.4°F (38°C) or higher, this is considered a medical emergency.
- Action: Do not give the baby any fever medication. Call your pediatrician immediately or go to the nearest emergency room. Newborns do not have fully developed immune systems, so even a slight fever needs professional evaluation.
For Babies 3 to 6 Months Old
If your baby is between 3 and 6 months old and has a temperature up to 102°F (38.9°C):
- Action: Call your pediatrician to report the fever. They may recommend bringing the baby in for a checkup or advise you on proper dosing for infant acetaminophen (paracetamol).
For Babies 6 Months and Older
For older babies, doctors often focus more on how the baby is acting rather than the exact number on the thermometer.
- When to treat: If the fever is making them fussy, uncomfortable, or preventing them from sleeping, you can offer infant ibuprofen or acetaminophen (always check with your doctor for the correct weight-based dosage).
4 Natural Ways to Keep Your Baby Comfortable
- Keep them Hydrated: Offer extra breast milk or formula. If they are over 6 months, you can offer small sips of water.
- Dress Lightly: Do not bundle a feverish baby in heavy blankets. Dress them in a lightweight, breathable layer (like a cotton onesie).
- Keep the Room Cool: Ensure the room temperature is comfortable, not too hot or too cold.
- Lukewarm Sponge Bath: A lukewarm (not cold!) sponge bath can help bring their body temperature down slightly. Never use cold water or ice, as shivering can actually raise their internal temperature.
When to Call the Doctor (Regardless of Age): Always call your pediatrician if the fever lasts more than 3 days, if your baby is extremely lethargic, unresponsive, having trouble breathing, or has a rash that doesn’t fade when you press on it.
