Your child’s fever: turning down the heat and when to worry

Child-sick-fever-jpgA fever is a sign that your child’s body is trying to fight an infection. A child’s fever can be caused by bacteria (some ear infections or strep throat) or by a virus (colds or the flu). Some childhood diseases also can cause a fever. It’s helpful to remember that a fever is your opportunity to know that your child is sick and needs care.

A child’s “normal” temperature varies and can depend on age, time of day and rate of activity. The first thing to do if you suspect a fever is take your child’s temperature with a digital thermometer. For infants, always use a rectal digital thermometer. You can use an oral or ear thermometer when your baby gets older.


An infant’s normal temperature is a little higher than in older children. In a newborn, a rectal temperature above 100.4 indicates a fever. If your baby has a fever during the first 8 weeks of life, we need to see you ASAP in the office or go to the ER if it’s after office hours.

Older Babies and Children

If your child has a fever and is not younger than two months, there are some ways to make him or her more comfortable. You may use acetaminophen to reduce your child’s fever. Once your child is older than 6 months, you may use ibuprofen OR acetaminophen but use only acetaminophen until your child reaches six months of age. Offer plenty of liquids to avoid dehydration. Do NOT overdress your child or give an alcohol bath.
