The Best Baby Thermometer 2020
Best Baby Thermometer 2020: Rectal
Last Updated: Best Baby Thermometer 2020: Rectal. . After comparing and testing more than 15 different thermometers, we picked the Vicks Baby Rectal Thermometer (
$18.45 $16.68) as the best rectal thermometer for babies. It is easy to use and designed with a short probe to make sure it isn’t inserted too far (ouch!).
If you have an older child (over a year of age), you don’t have to use a rectal thermometer, so scroll down to find our recommendations for both a conventional oral thermometer and a high tech thermometer and app.
The Vicks Baby Rectal Thermometer is intended only for use as a rectal thermometer. It reads out the temp in only ten seconds, making it impressively fast. Parents note the thermometer is also very accurate when compared with a hospital grade thermometer—plus it’s affordable.
Best Oral/Underarm Baby Thermometer
The Vicks ComfortFlex Digital Thermometer (
$14.99 $9.98) is both affordable and accurate. It takes oral, underarm and rectal temps. We only recommend using oral or underarm thermometers after one year of age. Because fever in babies under one year can be significantly more dangerous than in babies over one, pediatricians prefer parents use a rectal thermometer for the most accurate reading.
After one year of age, any temperature (taken orally or underarm) of over 100° F should be considered a fever reported to your child’s doctor.
Best High Tech Baby Thermometer
If you’d like to your track your baby’s temperature on a phone app, the Kinsa Smart Thermometer () does just that—the thermometer connects via Bluetooth to your iOS or Android phone.
We found the Kinsa to be accurate and the app well designed. If your child has multiple illnesses (or you have more than one baby), the app helps keep track of all that, including medications. Accuracy on the Kinsa is excellent.
The latest version of the Kinsa thermometer now displays the temperature right on the device—an improvement over the previous version that required a wired connection to a smartphone.
