Buying Guide for Baby Thermometers

Why buy a baby thermometer?

Overall, you want a reliable baby thermometer to track fevers and give your baby the best care. But there are things beyond body temperature that you might want to track when caring for a baby, including bath water temperature, bottle temperature, and nursery temperature. It’s very important to have a thermometer to monitor these things at home.

What should you look for in a thermometer?

  • Intended Use: Take note of what you need in a thermometer. You may be going on a trip and are concerned you’ll need more than a thermometer. Kits can be a great solution! Perhaps you have an infant whose temperature you need to take rectally. Do you need a thermometer for the bathwater, the baby’s body, or both?
  • Functions: What do you want out of a baby thermometer? Some thermometers store as many as 50 readings, read multiple surfaces, feature HD LCD screens, and give high-fever alerts. Rectal thermometers feature over-insertion gauges and flexible tips. If you list the features you want in a thermometer, you may have an easier time deciding on a product.
  • Extras: Look for baby thermometers with a storage case. Also helpful is an included battery, so you don’t have to research the correct, tiny battery type. Beyond that, check for products with manuals. There’s not worse than having a sick baby and a new thermometer than you’re struggling to use. Some even include a safety and wellness guide; it never hurts to get more input.

Which type of baby thermometers are best?

The answer changes depending on the patient’s age. For infants, especially newborns, rectal baby thermometers will give the most accurate readings. As babies age into toddlers, digital thermometers work great used in the armpit. Modern infrared forehead thermometers still make a reliable solution, too, but are most accurate when used on older toddlers, children, and adults.

Our Picks for the Best Baby Thermometers

Best Overall

GoodBaby Forehead Thermometer

A great thermometer that offers some high-tech features but is easy to use.

Pros: The GoodBaby forehead thermometer for babies and adults has numerous desirable features for quick, no-contact temperature measurement. It uses advanced technology for highly accurate readings of body temperature and room and surface temperatures. The infrared-powered thermometer features a backlit HD LCD screen to indicate normal (green), high (orange), or very high (red) temperatures. The tool also beeps to communicate temperature range, a feature you can mute. Bonus features include memory storage for up to 35 readings, Celsius and Fahrenheit units, a battery, and a storage pouch.

Cons: It may require about 20-30 minutes for the infrared thermometer and child to acclimate to the same room temperature for an accurate reading.

Bottom Line: The GoodBaby has a lot of parents’ positive feedback behind it as a reliable and easy-to-use thermometer. It works for all ages and can be used to get a quick temperature read on bodies and objects.


Best Bath Thermometer

Famidoc Baby Bathtub Thermometer

This toy thermometer makes bath time safer and more fun for you and your baby.

Pros: This colorful toy in the tub might inspire your baby’s first smile. It makes bath time for your baby safe, too. Give it a little shake to activate the thermometer and change the bathwater temperature as needed. The toy’s LCD shows the water temperature with updates every five seconds. It will also signal COLD or HOT if the temperature reads at or below 89.6 degrees and at or above 102.2 degrees Fahrenheit. The Famidoc baby bathtub thermometers vary in color and shape. Choose between a blue or purple stingray, a short orange cylinder resembling a clock, and a yellow rubber duck.

FridaBaby Quick-Read Digital Rectal Thermometer

A rectal thermometer with an insertion stopper for an easy 10-second read.

Pros: While you may want to avoid using a rectal thermometer for your and your infant’s sake, it’s the approach recommended by the American Academy of Pediatrics (AAP). If you’re nervous about using a rectal thermometer on your infant, know you’re not alone. FridaBaby designed this quick-read tool with you and your baby in mind. It includes an insertion stopper with an LED light to prevent mishaps and a flexible tip to make the 10-second read as comfortable as possible.

Cons: Some parents feel concerned about using a rectal thermometer on their newborns. If that’s the case, consult with your pediatrician for alternatives.

Also, it stores up to five readings, a detail that can come in handy if your baby is sick.


Best for Budget

This three-in-one thermometer is practical, accurate, and easy on the wallet.

Pros: Here’s an affordable baby thermometer that can be used orally, rectally, or in the armpit. This three-in-one thermometer gives an accurate reading within 30 seconds and beeps when the reading is complete. Importantly, this thermometer prioritizes comfort along with accuracy. The flexible tip and over-insertion gauge assist in creating uneventful temperature-taking for both you and your baby.

Cons: It takes approximately 30 seconds until the thermometer can deliver an accurate reading, a short amount of time that feels like a long time to wait.

Bottom Line: What we like about the Safety 1st thermometer is its streamlined design. Safety 1st specially made the thermometer so you can use it in three ways, but its features are straightforward.
