7 Best Thermometer For Infants That Are Quick, Effective & Accurate: 2020 Review

(Last Updated On: April 1, 2020)

There’s nothing worse than hearing your little one cry and being unable to do anything about it. They can’t tell you when they feel unwell and it can be such a difficult time for us moms. The most reliable way to determine if your baby is sick is with the best thermometer for infants. It is certainly a good investment.

Types of Baby Thermometers

Babies need specific types made just for them. There are even different types to consider, depending on the situation.

Rectal Thermometers

If you want accuracy, a rectal one is the way to go. They’re uncomfortable, yes, but they’re also an effective way to understand your baby’s sickness. Try one with a flexible tip and a wide base to prevent you from inserting it too far.


These are quite new, and understandably expensive. Infrared technology is used to scan and measure the temperature of the temporal artery without even touching your baby. That makes them safe and accurate, especially for kids over 3 months.


Looking at the temperature from the armpit is the least accurate option, but also is the least invasive. Usually these are a last resort if you can’t use any of the others. For the most part, under the tongue thermometers are generally a better choice.

Ear Canal

Checking the ears for the temperature is also not very invasive and easy to use. For a child over 12 months old, this will work great. Kids younger than 12 months won’t have wide enough ear canals to get a reading.


These are safe and easy, and only placed under the tongue. Oral ones work great for kids over 4 years though.


Young babies can use these, which are built into pacifiers. I thought they sounded pretty great, but doctors actually say these are fairly unreliable.

Some General Guidelines When Choosing The Top Baby Thermometer

When should I use a certain type? Not all kids can use every one, so it’s important to consider different factors.

While rectal ones are the most accurate, they may be better for your baby rather than an older child.

Oral ones are accurate too, but are better for older kids who are able to keep them in their mouth.

Forehead thermometers are great for all ages, and along with armpit ones , can be used if your baby has a problem like diarrhea. As long as your bub is a year old, you can even try an ear thermometer. These usually replace rectal thermometers over time.

Finally, no matter what type you buy, avoid anything with mercury in it. They can be toxic, which is the last thing you want!


Your baby can’t tell you when they don’t feel well, so it’s up to you to figure things out. It’s important to get the proper temperature right with any one of the best thermometers for infants. Take a breath and try not to worry too much; within a few seconds, you should have your results so you can help your baby be healthy again!
