Fever in children
Fever is not an illness. In fact, the body makes heat to kill germs. It’s natural to worry when your child has a fever. If you cannot reach your Doctor after hours, call the IEHP 24-hour Nurse Advice Line.

How to take your child’s temperature

 Infants (less than 3 months): use a digital thermometer in the baby’s rectum (bottom). Do not take the temperature in the infant’s ear.

 Babies (3 months – 2 years): use a digital thermometer in the baby’s rectum or use an electronic ear thermometer.

 Toddlers (2 – 3 years): use a digital thermometer in the child's rectum or use an electronic ear thermometer.

 Children (3 years and up): use a digital thermometer in mouth or ear.

Make sure to read the thermometer’s instructions. Do not use a mercury thermometer.

When to call your Doctor

Call you Doctor if your child has a fever and:

 Constant diarrhea or vomiting

 Earache or pulling at ears

 Sore throat

 Dry mouth or won’t drink fluids

 Severe rash or skin infection

 Fever comes and goes over a few days

 If your baby is less than 3 months with a rectal temperature of 100.4 degrees or higher for 2 days or longer.

 If your older child has a temperature of 102 degrees or higher for 3 days or longer.

Ways to help your child feel better

 Give your child lots of liquid

 Keep your child’s room cool

 Place a cool washcloth on your child’s forehead

 Give your child a sponge bath with luke-warm water.  Do not use cold water, ice, or rubbing alcohol in their bath. That can cause rapid body temperature changes.
