Use of Thermometers: Fever

DISCLAIMER:  Elevated body temperature in a child with a chronic illness requires special attention.  The information in this article does not apply in this situation.  If your child is under 3 months old and/or has a long term illness, you should seek medical treatment right away.

 Understanding Use of Thermometers in Fever Management

Fever is likely to be the most common reason you call your doctor or schedule a visit for your child. Elevated  body temperatures during an illness is a common cause of parental worry.

So what is fever? Fever is a rectal temperature of over 101 degrees Fahrenheit or over a 100.4 in infants under the age of 3 months.  I would suggest a top quality clinical grade digital infrared thermometers and measure the temperature at the forehead, temple, behind the ear, or in the ear canal.  Using a digital thermometer device like that will be easier on everyone, especially if you practice with it ahead of time.


Fever is also a normal body response to help fight infection. Usually fever is short-lasting and is very unlikely to cause any seizures or brain damage. Fever boosts the immune system helping a child fight off the bacteria or viruses causing the illness.  That way fever helps your child recover from illness faster.

Again, this article applies to otherwise healthy children. Seek medical attention right away if your child’s fever is linked with a chronic illness.
