User Experience

In my experience, this unit is straightforward and user-friendly, with a few minor drawbacks in its design. The battery installation process could have been simpler, as the cover is tough to remove and lacks a string for easy battery release. Once I figured out the correct button duration for temperature readings, it worked efficiently for measuring body temperature. This device is especially useful for children and fidgety individuals, as it quickly provides accurate results with a single button press. Despite the difficulty in opening the battery compartment, the lightweight and easy-to-use nature of the product makes it a valuable addition to my household.

iProven Infrared Lens Thermometer

Best Infrared Thermometer for Baby

This thermometer can be used as a forehead thermometer. It takes a reading quickly within 1 second at a distance of 0.4 to 2 inches. Operating the device is a breeze since all you have to do is press a single button; it leaves little room for confusion.

It beeps after the reading is taken, so you know that it’s done, and it sounds an alarm when a fever is detected. The temperature display is backlit, so you can view it in the dark, and the display is large and centralized, so you probably won’t have any trouble reading the numbers.

Pros

  • Easy to use.
  • The display is large and backlit.
  • There is a fever indicator.
  • Waterproof and easy to clean.

Cons

  • You cannot turn off the beep.
  • It’s a more expensive option.

Personal Perspective

Best thermometer I've ever used! This thermometer is incredibly easy to use - just pull the trigger and it does all the work, providing consistent and accurate results. It's lightweight and comfortable to hold, making it much less stressful when dealing with a sick child or checking on a sleeping relative. No more struggling with traditional stick thermometers; this is the perfect tool for quick and stress-free temperature checks.

Exergen Temporal Artery Thermometer

Best Temporal Artery Thermometer for Baby

Little kids are constantly getting ear infections, so it’s nice to have an option that allows you to easily and comfortably take your child’s temperature when they’re sick with one.

While ear thermometers can be inaccurate during ear infections — or plain uncomfortable to the inflamed ear — a gentle swipe across the forehead with this thermometer will give you a reading that has been proven by Harvard Medical to be more accurate than ear temperatures. Another study also showed it was as accurate as a rectal temperature, which has always been the standard for infants.

An indicator will tell you if the scan was incorrect (ensuring accuracy), and a backlit display will let you read the result even if the room you’re in is dark. And with a programmable beeper, you can decide whether you want it to make noise or not, depending on how sensitive your baby is to sounds.

Pros

  • It’s highly accurate.
  • You can use it on a sleeping baby.
  • It has a backlit screen for night use.
  • You can program it to beep if desired.

Cons

  • There’s no colored fever indicator.
  • The display is a little small.
  • It’s one of the pricier options.

Community Feedback

Definitely a helpful tool for families, this thermometer is easy to use and provides accurate temperature readings. I've found it to be particularly helpful with my toddler who doesn't mind it at all, and even tries to take his own temperature. The instructions could be clearer, especially regarding shifting between scanning mode and other functions, but once figured out, it's quite simple. The battery cover can be a bit tricky to remove, requiring more force than expected.

Braun Digital Ear Thermometer

Best Ear Thermometer for Baby

Though ear thermometers are quick and easy to use, they can be inaccurate if positioned incorrectly. This thermometer solves that problem by including visual and audible signals to indicate that it’s positioned correctly, ensuring an accurate read every time.

The tip also pre-warms to prevent readings from being influenced by external factors, and the flexible tip ensures your baby stays comfortable. Readings are taken in seconds, meaning you won’t have to wrangle your baby for very long to learn their temperature.

Pros

  • It’s fast.
  • It has a positioning aid for accuracy.
  • You can choose between Celsius and Fahrenheit.
  • The tip is pre-warmed.

Cons

  • It requires disposable lens filters (additional money).
  • The screen is not backlit.
  • There’s no audible indicator after reading is complete.
  • There’s no fever warning indicator.

First-Hand Impression

When I received this thermometer as a gift, I was impressed by its accuracy and ease of use. The heated tip provides accurate readings, and I appreciate the memory function that stores the last recorded temperature. It's also convenient that it uses AA batteries, which are easily accessible. However, I find it disappointing that the screen is not backlit, making it difficult to read in a dark room, and that it only remembers the last recorded temperature, unlike other thermometers I've used. Additionally, the device requires plastic lens covers, which are meant to be replaced with each use, but I've found that cleaning them with alcohol after each reading works just as well.

iHealth No-Touch Digital Forehead Thermometer

Best Non-Contact Baby Thermometer

This infrared device will measure any temperature in one quick second — without risking cross-contamination since it doesn’t even have to touch a person to make a reading. You can use it for babies, children, or adults.

It has a sleek display with a quiet vibrating indicator if fever is detected.

The single button makes operation a breeze, and since you don’t even have to touch your child to take their temperature, you can do so without disturbing your little one’s sleep.

Pros

  • Designed for all ages with environmental temperature compensation sensor.
  • With memory feature.
  • It reads instantly.
  • Vibrating fever alert indicator.
  • Simple sleek design.

Cons

  • Requires 2 AAA batteries.

User Experience

From my experience, this touchless forehead thermometer is a fantastic addition to any household, especially with young children. It's accurate and works quickly, making it perfect for squirmy babies and toddlers who aren't fans of traditional thermometers. The soft display light and lack of beeping noises allow for easy, non-disruptive use at night. I've found the thermometer to be durable and long-lasting, even when dropped by curious little hands. The simple one-touch operation and quick readings make it a breeze to use, and the included batteries were a nice bonus.

No Touch Thermometer

Best Thermometer for Whole Family

Fevers can spread like wildfire throughout a home, and you don’t need to be rummaging around for multiple thermometers when everyone is sick. With this forehead and ear thermometer, you can take everyone’s temperature quickly and safely.

Simply choose which reading you’d like with the press of a button. The temperature is taken in a single second and displayed on the digital readout so there’s no second-guessing. It even has a fever alert and will turn red at high temperatures.

We love that you can use the forehead reader on your littlest baby and then the ear reader on your older children. If you’re a mom with lots of littles running about, this thermometer makes life a lot easier.

Other features include Celsius to Fahrenheit conversions and a storage capacity of 35 readings. You’ll be able to use it for years to come.

Pros

  • Multiple modes allow for safe and accurate readings on anyone of any age.
  • Store up to 35 temperature readings.
  • Fever alarm lets you know when baby’s temperature is too high.

Cons

  • Readings can be inconsistent as you can use this thermometer in two ways.

Great thermometer with multiple functions! I've used this thermometer in both the ear and on the forehead, and it consistently gives accurate readings. The display is easy to read and understand, and it's super simple to use. I appreciate the speed at which it takes temperatures, especially with my squirmy one-year-old. It even works on food and room temperatures, making it a versatile addition to my household.

Amplim Hospital Medical Grade Infrared Digital Thermometer

Best Clinically Tested Thermometer

When your baby is sick, you don’t have time to double or triple check their temperature. You need accurate and consistent results immediately. This clinically tested thermometer can be relied on to give clear and fast measurements.

A lot of thermometers claim to work this way, but we like the scientific backing of this one. You can never be too careful when it comes to the health of your baby and family.

This thermometer takes forehead measurements. Forehead readings are especially good for when your baby is fussy or asleep. Simply swipe the thermometer across your baby’s forehead for a super quick measurement.

The backlight will flash green if your baby’s temperature is in the safe zone. If your baby has a fever, it will turn bright red. With this system, you can get the answers you need and take action fast.

If you’re looking for an item with coverage, this thermometer is FSA and HSA eligible.

Pros

  • Backed by CE and FDA standards, so you can be assured of accurate results.
  • FSA/HSA approved.
  • One minute auto shut down which is battery efficient.
  • Fever-detection system alerts you to high temperatures.

Cons

  • Reads forehead measurements only.

Great non-contact thermometer with an affordable price and compact design. This thermometer provides accurate readings and is super easy to use with just one button, making it perfect for use with little kids. The bright display allows you to easily read the temperature in either Fahrenheit or Celsius, and it even has different beeps to indicate if your temperature is too high or too low. Although the battery cover may be a bit frustrating to remove, it uses regular AAA batteries, which is convenient.

Vicks Baby Rectal Thermometer

Best Rectal Baby Thermometer

This thermometer was designed with your baby’s body in mind. The short probe guards against over-insertion, which could cause accidental harm to your baby. And you’ll only have to keep them still for about 10 seconds before it gets a reading and shows it in the backlit digital display.

Parents who use this thermometer swear by its accuracy and ease of use. If you’re hesitant to take a rectal thermometer reading on your baby, with this device, you’ll know you’re getting the most accurate reading in a non-invasive and comfortable way.

Pros

  • It’s accurate, so you can trust the reading.
  • Works quickly.
  • The short probe prevents accidental injury.
  • It has a backlight.

Cons

  • Because it’s for rectal use only, this isn’t very versatile.
  • There’s no audible indicator to let you know when the reading is complete.

First-Hand Impression

I recently started using this small and easy-to-use thermometer for my newborn baby, and it has been gentle enough not to cause any discomfort. However, I was disappointed when the battery died after just a few months of use. It seems I'm not alone in this experience, as others have also mentioned the short battery life and difficulty in finding a suitable replacement. While I appreciate the design and convenience of this thermometer, the battery issue has made it less reliable than I had hoped. Unfortunately, the product description doesn't provide information on the battery type, leaving me unsure about whether to replace it or simply purchase a different thermometer.

 

Do You Need a Baby Thermometer?

Babies need so much extra gear, so it’s easy to assume that a baby-specific thermometer is just another gimmick. Though you may be tempted to use a thermometer you already have, that would be a mistake. The differences between standard thermometers and baby thermometers are noteworthy:

  • Regular oral thermometers aren’t appropriate because babies cannot hold them under their tongues. You may think you can use it to monitor a temperature under the arm, but that’s one of the least accurate ways to measure a baby’s temperature (1).
  • If you have an ear thermometer, you need one manufactured for a small ear canal to ensure an accurate reading.
  • If you have an older glass mercury thermometer, it can be dangerous if it breaks and the mercury is inhaled. Mercury exposure has been linked to neurological problems and other serious health issues (2).

Purchasing a thermometer designed with babies in mind will help keep them safe and ensure you get an accurate temperature reading every time you suspect a fever.

Types of Baby Thermometers

You have many different options when choosing a thermometer for your baby (3):

Digital Thermometer

A digital thermometer has an electronic sensor on one end and a digital readout on the other. You can use digital thermometers in several ways: orally, rectally, and axillary (under the arm).

Safety First

Identify and label your digital thermometer for either oral OR rectal use (not both) due to sanitary reasons. If you are taking rectal temperatures, use a thermometer with a tip designed for rectal usage.

Digital thermometers are not the best choice for babies because:

  • It’s near impossible to take an oral temperature on a baby.
  • Axillary temperature is one of the least accurate ways to take a temperature.

Glass Thermometer

This looks like the typical thermometer you may remember from your childhood. You place it under your tongue, and the mercury rises to indicate your body’s temperature.

However, modern thermometers no longer use mercury, but some are manufactured in a similar design with a non-mercury substitute.

Safety First

Mercury is considered a hazardous waste substance. If you have an old mercury thermometer in your home, dispose of it properly so your family does not come into contact with the mercury (4).

Just like with digital thermometers, you can use glass thermometers to take an oral, rectal, or axillary temperature.

Ear Thermometer

Ear thermometers take a baby’s temperature quickly by sensing the infrared heat that comes from inside the ear.

However, there are some factors involved in getting an accurate reading:

  • The ear must be clear of wax build-up.
  • You must insert the thermometer correctly.
  • It must be appropriately sized for the child’s ear canal.
  • The child should be older than three months to ensure accuracy.

Temporal Artery Thermometer

Also known as a “forehead thermometer,” this type of thermometer measures the infrared heat that comes off the head by sensing the temporal artery in the forehead.

Recent research indicates that these thermometers are accurate enough for use with newborns (5).

How to Choose a Baby Thermometer

When choosing a baby thermometer, keep the following things in mind:

Accuracy

This is the most important factor, above all else. When you’re trying to detect a fever in your child, you need to know that the temperature you’re getting is correct. Choose a thermometer that medical experts agree is accurate.

Consistency

There’s nothing more frustrating than taking your baby’s temperature and then retaking it only to get a wildly different reading. When used correctly, readings should be the same over and over again.

Suitable for Babies

If your child is under the age of one, purchase a thermometer especially intended for babies.

Fahrenheit or Celsius

Which unit of measurement do you prefer to use? Make sure the thermometer you choose will give you a reading in the proper units to avoid confusion.

Speed

Babies don’t have much patience for poking and prodding. When choosing a thermometer, pick one that will only require a few seconds of wrangling.

You don’t want to hold them down for a full one-minute reading, which will only make it more likely you’ll make a mistake and get an inaccurate reading.

Complexity

This is a matter of personal preference, but do you want a thermometer that’s easy to use? Or do you like special features? The touch of a single button easily operates many thermometers.

Others have additional buttons that allow you to save readings and display history. If you’re only trying to take your baby’s temperature, our personal take is that simple is best.

Sound

Thermometers that beep to alert you that the reading is complete can be very helpful. However, some parents prefer a silent thermometer that won’t wake a sleeping baby.

Backlit Display

This is essential for being able to see the thermometer’s reading in the wee hours of the morning when you’re snuggling your sick babe.


How to Use a Baby Thermometer

Remember

No matter how simple your thermometer appears, read the instruction booklet to make sure you’re using it correctly.

The way you use your thermometer will depend on the kind you have:

  • For a rectal reading: Gently insert the tip only about a half-inch to an inch into your baby’s rectum (not simply between the cheeks!) and wait for the beep. A dab of lubricant can help ease the process.
  • For an underarm reading: Remove clothing on one arm, place the thermometer high into the armpit, and hold the arm back in place until the reading is complete. Make sure that only skin touches the thermometer tip.
  • For a temporal artery reading: Place the thermometer on the forehead between the eyes, and press the button when your baby is still for a second. There’s no need for the device to touch your baby’s skin.
  • For an oral reading: Position the thermometer under the tongue and ask the child to hold their mouth closed until the reading is complete. Make sure the tip is touching the tissue of the tongue and not up against the teeth or in the open air.
  • For an ear reading: Gently stabilize your child’s head, pull the ear up and backward to open the ear canal, and insert the device tip inside. Be careful not to jam it in, but at the same time, ensure it’s touching the ear evenly, with the tip straight and not pointing up or down. Press the button, wait for the beep, and remove. You may want to use a cotton swab with some alcohol to sanitize the tip after use.

Oral and ear readings are best used for older children (1 to 3 years old), and rectal or axillary readings are best for newborns and younger babies.

It’s a good idea to get two different kinds of thermometers so you can confirm any reading. If the temperatures you get are quite different, take an average of both or wait a while to take another reading.

It’s normal for even very accurate devices to have slight variations, so avoid taking temperatures repeatedly. You’ll only stress yourself out, and your baby might not appreciate the extra poking and prodding.

FAQs

Are No Touch Thermometers Accurate for Babies?

Yes, no touch thermometers are accurate for babies. In fact, many official studies agree that no touch thermometers are accurate for babies about 97% of the time.

These thermometers are perfect for taking everyone’s temperature, too. If someone in the family is feeling under the weather, a no touch thermometer can give anyone an accurate reading.

Is Ear or Forehead Thermometer More Accurate for Babies?

A forehead thermometer is going to give you a more accurate reading than an ear thermometer. Still, it’s important to follow the directions of the type of thermometer you have to the letter.

Using either one of these thermometers incorrectly can give you an incorrect reading, no matter what the quality of the tool is.

How Do I Know If My Baby Has a Fever Without a Thermometer?

There are other symptoms besides just a hot temperature to watch out for if you think your baby has a fever. Are they not feeling like themself?

Do they seem much more cranky than usual, or are they tired all the time? These can be signs of a fever, too. Flushed skin can also indicate a fever.

What Kind of Thermometer Do Pediatricians Use?

Typically, pediatricians use the most accurate thermometer available. This would be a rectal thermometer, which you can also buy for at-home use.

In fact, some doctors recommend you use a rectal thermometer to take your child’s temperature until their mid-toddler years. You can ask your pediatrician more about rectal thermometers or watch informative videos about how to use them correctly online.

What Is the Best Type of Thermometer for a Baby?

Either a rectal thermometer or a forehead thermometer is best for a baby. Both of these types of thermometers give incredibly accurate readings.

Ear thermometers can give very accurate readings, too, but make absolutely sure you’re using this type correctly if you buy an ear thermometer.


The Bottom Line

While there are plenty of choices on the market, our top pick for the best infant thermometer is the Amplim Medical Grade Non-Contact Thermometer. Not only is the display large and easy to read, but it changes color to notify you of a fever, and beeps when the cycle is complete to let you know a reading has been taken.

It can also switch between Celsius or Fahrenheit and can be used as a forehead thermometer (for your infant) or an ear thermometer (for everyone else). It’s the perfect all-around, easy-to-use, and accurate thermometer for your whole family.

Having a sick baby is never fun, but knowing you’re able to monitor their temperature accurately can give you peace of mind.
