Before you purchase a thermometer, you have to check if it’s the best type of thermometer for babies. Unlike one adult’s use, babies and toddlers need a thermometer with the right features. The following are some thermometer types and its functions:


Also known as temporal artery thermometers, this is one of the latest models in the market. It uses an infrared technology to measure the temperature on a person’s forehead.

This is very convenient and safe to use since it doesn’t require any physical contact. Many hospitals and clinics now use this thermometer since it will not require repetitive sanitation.

Take note that forehead thermometers are only ideal for babies at least three months old.


Oral thermometers are safe to use for kids that are at least four years old. Avoid using oral thermometers on babies as it can become a choking hazard. It will also be challenging to get accurate readings with this type of thermometer on a baby.


Ear thermometers are widely used among babies since it gives an accurate reading. This thermometer has an ear probe that fits inside a child’s ear canal. It’s a little tricky to use, but it’s much safer for babies that are at least six months old.


Axillary or armpit thermometers are useful for adults. However, for babies, it may not be as accurate as rectal types. Nevertheless, they can be used for children too.


Rectal thermometers are very important thermometers for babies. It’s available in most drugstores, though using it can be challenging when the baby is cranky. Also, most rectal thermometers have flexible tips for easy angling.

Performance and accuracy

No matter what type of thermometer you’re using, you must opt for one with excellent accuracy and performance. An accurate thermometer should yield a 0C reading when submerged on ice water.

Also, if the thermometer is starting to register inaccurate readings, a battery replacement should fix the problem. If not, the thermometer’s chip probably reached its end life.


Above all, the thermometer you’re going to use should be safe for your baby. Avoid thermometers made of glass or those that contain mercury. Also, no parts should be removable that can cause choking.

When in doubt, it pays to ask the doctor about the safest option for your baby.

Price point

Lastly, look for a thermometer that falls within your preferred price point. You don’t have to spend a fortune on a baby thermometer, but you have to ensure that the one you’re getting is accurate.

Still, you wouldn’t want to buy a very cheap thermometer. Dirt cheap types are likely to be less accurate than other types.
