The younger the child, the more the worry. Tiny babies have immature defenses against germs. Any fever in a baby under three months should be reported to your doctor, regardless of the hour of the day or night. Likewise, if your child is becoming increasingly drowsy, pale, and lethargic and the fever persists, call your doctor. Never use aspirin for fevers in children and teens less than 20 years of age.
Some parents choose to alternate between the acetaminophen and ibuprofen.
This is helpful if your child tends toward febrile seizures, and is not necessary for most illnesses. Use only recommended doses. Let your child suck on popsicles and sip cool, clear liquids all day. Children often do not want to eat when they are sick and feverish, but they must drink. Offer fluids frequently in small amounts.
