Flushed skin, a sweaty back and a general feeling of discomfort are all tell-tale signs of an illness. These physical symptoms allude to a raised body temperature, but the only sure way to tell if your child’s running a fever is to take their temperature.
There are three types of thermometers: Digital thermometers can be used rectally, orally and axillary (under the armpit), while temporal artery thermometers read the infrared heat waves released by the temporal artery on the side of the forehead. There are also tympanic thermometers, or ear thermometers, that read the infrared heat waves released by the ear drum. But according to the American Academy of Pediatrics, digital rectal thermometers give the most accurate readings for children three years or younger.
On the list of least glamorous acts of motherhood, taking your child’s temperature through their rectum definitely makes the top ten. That being said, there are some best practices that make the experience a little more comfortable for your baby or toddler. First, start by cleaning the end of the thermometer with either rubbing alcohol or soap and cool water. Once fully cleansed, apply a bit of lubricant (petroleum jelly works fine) on the end of the instrument so that it goes in smoothly. Finally, with your child tummy-down across your lap or knees to belly on the changing table, insert the thermometer between one half to a full inch inside the anus for one minute for a proper reading.
Believe it or not, though, the hardest part of taking your child’s temperature is finding the best rectal thermometer for your tot. Here are some of the most popular options out there.
