Best Baby Thermometers of 2019
These thermometers can help you figure out if your little one has a fever.


Your baby has been out of sorts all day. When theyâre awake, theyâre fussing, and when theyâre napping, itâs not for long. Are they teething? Having an off day? Or coming down with something? A thermometer can help you gauge whatâs up by telling you if your little one has a fever and if a call to your pediatrician might be in order.
Do You Need a Baby Thermometer?
Gone are the days of putting a palm to your babyâs forehead to try to figure out if your little one is running hot. Keep a thermometer handy to take babyâs temperature, and youâll be able to truly determine if your child needs a dose of medication, to see the pediatrician or just watchful waiting.
What Types of Baby Thermometers Are There?
Baby thermometers basically fall into these three basic types:
- Digital thermometers: Digital thermometers take a minute or less to record a temperature. They can be held under the tongue or in the armpit or inserted into the anus. And speaking of⊠We hate to break it to you, but itâs important to know that rectal temperature is the the gold standard for newborns and even older babies and toddlers. Thatâs because having a baby or small child hold the thermometer still in their mouth is near impossible, and an armpit reading is the least accurate measurement. Before your child is six months old, a rectal thermometer is the only reliable measurement.
- Ear thermometers: Quick and generally comfortable, ear thermometers (a.k.a. tympanic thermometers) measure the temperature inside the ear and are safe to use on babies six months and older.
- Forehead thermometers: More accurately known as temporal artery thermometers, these thermometers are swiped across the forehead to read the temperature of the major vein located there. Itâs an easy, fast and non-invasive way to get a temperature on any child older than six months. Youâll typically pay more for the convenience factor of this kind of thermometer, though.
Note about pacifier thermometers: In theory, these sound awesome if your baby uses a binky. But donât even consider these. Why? Because your baby would have to hold the pacifier still for three to five minutes in order to get a reading. And, unless sleeping, most babies wouldnât do that. Plus, this type of thermometer is not recommended for newborns.
When to Call the Doctor if Your Baby Has a Fever
Itâs always good to keep in mind when you need to call the doctor for your childâs fever and when itâs OK to let it run its course. Per the experts, you should reach out to your pediatrician if:
- Your child is younger than 3 months and has a rectal temperature of 100.4 F (38 C) or higher.
- Your child is between the ages of 3 and 6 months and has a rectal temperature up to 102 F (38.9 C) and seems unusually irritable or lethargic, or has a temperature higher than 102 F (38.9 C).
- Your child is between the ages of 6 and 24 months and has a rectal temperature higher than 102 F (38.9 C) that lasts longer than one day but shows no other symptoms. If your child is exhibiting other signs and symptoms like a cough, cold, or diarrhea, you may want to call your childâs doctor sooner based on severity. And when in doubt, call.
Below are some thermometers you may want to consider adding to your medicine cabinet.
Affordable & Accurate
Why We Love It
âI love taking rectal temperatures,â said no one, ever. But it is the best way to get an exact temperature reading on your little one, and this inexpensive model is shaped so you canât over-insert it (the number one fear!) and only takes eight seconds to give a temperature reading.
Keep in Mind
Weâll admit it: those eight seconds can seem like an eternity when youâre trying to hold a squirming baby or deal with a bout of crying. But we promise after a few tries, the whole experience wonât be nearly as daunting as you might think.
Smart Phone Temp Taker
Why We Love It
Thermometers got techie, but this one is anything but intimidating. Simply take your childâs temperatureârectally, orally or under the armâand get a fast readout on the thermometer or on the Kinsa smartphone app. (You can even hand the phone over to your toddler to play a bubble-popping game on the phone while they wait.) Youâll get the results in eight seconds or less, and the free app will let you record other symptoms and notes to share with your pediatrician later. The app also provides advice based on the fever reading and your childâs age. Even better? Itâs powered by your phone so batteries arenât needed.
Keep in Mind
This thermometer can be used with or without the app, but the app is required for initial set up and use of smart features (symptom logging, advice, etc.).
Effortless & Effective
Why We Love It
Often used in pediatrician offices and hospitals, this just requires a simple swipe across the forehead to give a quick reading with minimal disturbance to your little one. Because of that, we especially like it for taking temps on a sleeping child. And itâs the next best thing to getting a rectal temp.
Keep in Mind
It takes some practice to get the forehead swipe exactly right, but after a few tries, youâll get it down. Also, if your child has a sweaty forehead, it could throw off the readingâin that case, youâll need to take the temperature by holding the thermometer behind their ear.
Modern Temp Tracking
Why We Love It
Thought Bluetooth was only good for your music speakers? Think again. Meet the FeverFrida, a wireless thermometer that allows you to remotely monitor your little oneâs real-time temp via a low-energy wearable Bluetooth device. Simply stick the non-irritating adhesive patch under your childâs arm and receive an alert on your phone when your little oneâs temperature starts to rise over a customizable preset number.
Keep in Mind
The app stores all of your temperature readings, which may come in handy during a visit to the pediatrician. You can also set an alert for medicine dosage.
Two-in-One
Why We Love It
Unsure whether youâll prefer an ear or a forehead thermometer for trying to take your little oneâs temp? This one has both. Thereâs even a backlit screen for easy middle-of-the-night reads.
Keep in Mind
If youâre using the ear mode, be sure to pull your little oneâs ear back and up and aim gently at the eardrum areaâitâll make for a much more accurate reading.
No-Fear Rectal
Why We Love It
Because of its bulbous shape, this rectal thermometer is a cinch to hold and impossible to push in too far. Itâs made to use on infants and children up to two years old. After 10 seconds, the thermometer beeps, indicating that the reading is complete.
Keep in Mind
This thermometer is waterproof, so you donât have to stress about how to clean it.
Speedy Reading
Why We Love It
Super-fast resultsâin two secondsâare generated by this non-invasive thermometer. And unlike other ear thermometers where the cold tip can cool the area leading to inaccurate results, the Braun Thermoscan has a pre-warmed tip so itâs a non-issue.
Keep in Mind
It might be difficult to get the thermometer in exactly the right position in the ear canal, which could give misleading results. Also, if your wee one is suffering from a painful ear infection, trying to get anywhere near their ears could be a problem.
Choosing Whatâs Right for You
Remember that the rectal thermometers can be used on newborns, but youâll need to wait until at least six months of age to use the forehead or ear thermometer and until four years old to use a thermometer in the mouth or under the arm. The right thermometer for you and your family is the one you will feel comfortable using during what can sometimes be a worrisome time. Armed with a thermometer and a good pediatrician, you can rest assured that your baby will get the care they need when they need it.
