A fever, defined as 100.4°F (38°C) or higher, is just our body's way of reacting appropriately to fight off an infection, and it means the immune system is doing what it's supposed to do. However, a fever in a newborn is treated as a medical emergency to rule out potentially dangerous infections needing prompt treatment.
If your baby is younger than 2 months,a fever of 100.4 warrants a trip to the emergency department.
If your baby is between 2 and 3 months,call your pediatrician right away for guidance.
If your baby is older than three months,a fever can be monitored at home, with guidance from your pediatrician, if it persists past 24 hours.
How to help your baby's fever at home (3 months+)
Dress your baby in lightweight clothing and ensure their room is comfortably cool.
Avoid using heavy blankets or over-bundling.
Offer plenty of breast milk or formula to keep your baby hydrated. Water cannot be introduced before six months of age.
If they are fussy, you can offer infant acetaminophen to alleviate discomfort. Always follow the appropriate dosing guidelines based on their age and weight. Infant ibuprofen is not recommended until your baby is at least six months of age.
A lukewarm bath or sponge bath may help lower their temperature.
Most fevers are caused by viral infections requiring rest, time, and staying hydrated. Some can be caused by bacterial infections that may require antibiotics. If your baby's fever persists past 24 hours, it's a good idea to call your pediatrician.
