Overview

Fever is a symptom, not an illness. It is the body's response to infections and other illnesses.

Normal body temperature is about 98.6°F. It is usually lower in the morning and higher in the late afternoon. We call it a fever when the body temperature is 100.4°F or above when taken with a digital thermometer or forehead scanner.

Each child has a normal temperature range that may be different from any other child. Mild increases to 100.4°F can be caused by:

  • Exercising
  • Wearing too many clothes
  • Taking a hot bath
  • Being outside in hot weather

If your child is running a fever, the temperature reading may not be related to the seriousness of the illness. The way your child looks and acts is a better guide than the thermometer. Most children will be less active when they have a fever.

Most fevers can be treated at home. If your child doesn't seem to be very sick, it is fine to wait 48 to 72 hours and let the fever come down on its own.

How to Take Your Child's Temperature

Use a digital thermometer to take your child’s temperature. Other ways to measure temperature, such as ear probe thermometers, forehead temperature strips, or pacifier thermometers may not be as accurate. Glass thermometers are no longer recommended as they contain mercury.

Using a digital thermometer

A digital thermometer can be used rectally (in the bottom), in the armpit, or in the mouth, depending on your child's age. If your child is:

  • Under 4 months, take temperatures rectally. This method is the most reliable in infants. Watch our video “Taking Your Baby’s Temperature” for detailed instructions.
  • 4 months to 3 years old, rectal temperatures are still most accurate, but are not essential. You can also use a digital thermometer in your child’s armpit. Another option is to use a temporal scanner on your child’s forehead.
  • 4 years or older, take your child's temperature by mouth. Make sure he or she keeps the thermometer under the tongue until it beeps. Another option is to use a temporal scanner on your child’s forehead.

Symptoms

If you think your child has a fever, it's important to look for other signs that your child may be ill.

Babies with a fever may:

  • Cry or be more irritable than usual
  • Be listless or drowsy or more sleepy than usual
  • Eat poorly (loss of interest or frequent stops during feeding, weak suck)
  • Breathe faster than usual
  • Have mottled skin

Older children may:

  • Complain of body aches or a headache
  • Have difficulty sleeping or sleep more than usual
  • Have a poor appetite

Home Treatment

In most cases, you can safely take care of your child at home. If your child doesn't seem to be very sick, it is fine to wait 48 to 72 hours for the fever to come down on its own.

It can be hard to know when to call us about a fever, especially during cold and flu season. Home treatment is usually all that is needed for a fever of 100°F to 103°F as long as your child is:

  • Comfortable and alert
  • Eating well
  • Drinking enough fluids
  • Seems to be improving

Tips When Your Child Has a Fever

Follow these tips when your child has a fever:
  • Watch for signs of dehydration. Encourage your child to drink extra fluids or suck on Popsicles. Your child should be urinating at least every 6 to 8 hours.
  • Avoid making a room too warm or too cool.
  • Dress your child lightly and do not wrap him or her in blankets. Dressing lightly will help your child's body cool down.
  • Do not sponge-bathe an infant who has a fever. Do not use ice or rubbing alcohol on a child of any age.
  • Baths can cause unnecessary discomfort. If you do decide to give your child a bath, use only tepid water, bathe for 5 to 10 minutes, and thoroughly dry and dress your child comfortably.
  • Encourage quiet activities and rest.

Over-the-Counter Medications

Treating a fever won’t make the infection go away faster but it will make your child more comfortable.

You can use over-the-counter pain medications to reduce fever. Examples include ibuprofen (Advil) and acetaminophen (Tylenol). Follow the package dosing directions exactly. Download our Pediatric Dosage Guide for more information.

Talk to us before using both acetaminophen and ibuprofen to treat a fever. When you switch between two medicines, there is a chance you will give too much medication.

Safety tips when using nonprescription medicines:

  • Read and follow all labels on the bottle and box.
  • Give the maximum recommended doses. Do not exceed it.
  • Don’t give your child a medicine if he or she had an allergic reaction to it in the past.
  • If your child is less than 2 months old, do not give acetaminophen unless directed.
  • Do not give ibuprofen to infants under 6 months of age.
  • Do not give aspirin to anyone under age 20.
  • Do not give naproxen sodium (Aleve) to children younger than age 12 unless we prescribe it for you.

Causes

Common causes of fever in children are:

  • Colds, flu, chickenpox, and other viral infections
  • Infections of the ear, throat, or urinary tract
  • Other infections caused by bacteria or viruses
  • Immunizations: A low-grade fever can develop after a vaccination

Teething does not cause a fever. If your baby is teething and has a fever, look for other signs that your child may be ill.

When your child has a fever, remember the following tips:

  • How your child looks and acts (especially when the fever is down) is much more important than the thermometer reading.
  • Consider your child's other symptoms to help determine whether the illness is mild or more serious.
  • Although it may be scary when your child's temperature goes up, fever will not harm your child.
  • Children tend to run higher fevers than adults. The degree of fever may not indicate how serious your child's illness is.
  • Children with fever may be fussy, play less, or not eat as much as usual.
  • You can usually treat your child's fever safely at home.
