Where should a baby’s temperature be taken?

Today’s digital thermometers make taking a baby’s temperature simple with quick results. For best results in babies and toddlers up to 3 years of age, the American Academy of Pediatrics recommends taking the temperature rectally, by placing a thermometer in the baby’s anus. This method is accurate and gives a quick reading of the baby’s internal temperature. A newer method to measure temperature called temporal artery thermometry is also considered very accurate. It causes less discomfort than a rectal thermometer and is less disturbing to a newborn. It measures the temperature of the blood flowing through the temporal artery, on the forehead.

Taking the temperature under the arm (in the armpit) is called axillary measurement. It may be used to “screen” or get an idea about whether or not any child has a fever. If it shows a fever, the temperature should be rechecked by a more accurate method. Other types of thermometers, such as tympanic (ear) type thermometers, may not be accurate for newborns and need to be carefully positioned to get a precise reading. Skin strips that are pressed on the skin to measure temperature are not recommended for babies. Touching a baby’s skin can let you know if he or she is warm or cool, but you can’t measure body temperature simply by touch.

Always use a digital thermometer to check your child’s temperature. Never use a mercury thermometer. For infants and toddlers, be sure to use a rectal thermometer correctly. A rectal thermometer may accidentally poke a hole in (perforate) the rectum. It may also pass on germs from the stool. Always follow the product maker’s directions for proper use. If you don’t feel comfortable taking a rectal temperature, use another method. When you talk to your child’s healthcare provider, tell him or her which method you used to take your child’s temperature.

Taking your baby’s temporal artery temperature

Place the thermometer sensor in the middle of the baby’s forehead.

Press and hold the scan button.

Slowly move the thermometer across the forehead toward the top of the baby’s ear. Make sure it always touches the skin.

Stop at the hairline and release the scan button.

Remove the thermometer and read the temperature.

If a baby’s rectal or temporal artery temperature is 38^oC or higher, call your baby’s healthcare provider
