Our Picks: Best Baby Thermometer
The best baby thermometer on the market should be easy to use and should be able to take temperature quickly and accurately.
Because babies cannot express how they are feeling, a thermometer will help provide the insight you need and help you figure out when you should be calling your pediatrician.
We carefully chose these baby thermometers and listed them to help you easily determine which baby thermometer is best for your household and budget.
When To Call The Doctor
Sometimes it’s OK for a fever to run it’s course, and sometimes it’s not, so when do you call the doctor?
- When you child has a rectal temperature of 100.4 F or 38 C and higher and is under the age of 3 months
- For children aged 3-6 months the rectal temperature should not be higher than 102 F or 38.9 C, If they seem very lethargic and cranky plus have a temperature over 102 F then you should call the doctor.
- If your child is between the ages of 6-24 months and they have a fever over 102 F for over 24 hours then you should call your doctor. If the fever is accompanied by other symptoms such as diarrhea, cough or cold then you should call the doctor sooner.
Please keep in mind this is not a medical professional website and you should trust your pediatrician when it comes to the health of your baby. We can, however, help you choose some tools to help you keep an eye on your baby such as baby thermometers, video monitors and recommend baby apps to track your baby’s health.

Guide To Buying A Baby Thermometer
Different Types Of Baby Thermometers
All parents should have a thermometer on hand before the baby arrives. A temperature above 100.4 degrees before the age of 3 months is very concerning and requires urgent attention, and unfortunatey the “touch test” isn’t going to be very helpful in helping you in an emergency.
Children develop fevers for all kinds of reasons, from serious conditions to teething symptoms, and all high temperatures should be tracked and payed attention to.
For children over the age of 3, a temperature of over 102 degrees that is consistent for over 2 days requires a visit to the hospital.
That being said, there are a few different types of thermometers to consider purchasing.
Forehead Thermometers: For a really precise temperature reading, forehead thermometers are the best option. These thermometers are high tech and measure the temporal artery temperature on the forehead which can be used for newborns and babies and children of all ages.
Rectal Thermometers: The most accurate temperature readings come from rectal baby thermometers, though they are the most uncomfortable to use. These are the best thermometers for newborns up until about 3 months of age.
Oral Thermometers: Oral thermometers are safe to use and are simple too. Just place the thermometer under the tongue and wait for the reading to appear. These thermometers are better suited for children who are older than 4 due to the fact that they can hold still long enough for the reading to come through.
Ear Thermometers: For older babies who are over the age of 1, ear thermometers are a good choice. The placement inside the ear is important for this thermometer and a newborn will have too small of an ear canal opening for the thermometer to make a reading.
Pacifier thermometers: Pacifier thermometers are cute and they seem very practical, however they are not the most reliable and we suggest you stay away from these thermometers altogether.
Armpit Thermometers: Armpit thermometers are also rather inaccurate and not suggested to be used for any baby or child.
What To Keep In Mind When Purchasing A Baby Monitor
Baby Age: Not all baby thermometers can be used for any and every age. Rectal thermometers and forehead thermometers are the best for newborn ages. Oral thermometers require the child to stay still in order to get an accurate reading so these types of thermometers are better for older children.
Display: A large back lit display is important in a thermometer because you may not always be in a well-lit room when taking the baby’s temperature. It’s very common for babies to wake up at night with a fever and you wouldn’t want to make them more uncomfortable by bringing them into a lit room during the night.
Response Time: A thermometer that has a faster response time will be very handy because babies do not traditionally stay still. Fast response time can still provide an accurate reading while not needing the child to hold still.
Accuracy: It’s best to grab a thermometer that provides an accurate reading. This means that the pacifier style and the armpit thermometers and not the best choice for accurate readings.
Cost: While purchasing a very inexpensive baby thermometer is better than having no thermometer, investing in a proper thermometer is important. A better thermometer will mean more money needs to be spent, but perhaps you can cut corners elsewhere in the baby essentials budget because this one is not a space you want to cheap out in.
When Do You Need A Baby Thermometer
You should purchase a baby thermometer before your baby is born. In fact, it’s a great item to put onto your baby registry. Your baby could develop a fever on their very first night home, which can be very scary for parents. Having a thermometer on hand can put a lot of fears and worries to rest.
Babies are unable to tell you how they feel, and it can be difficult to tell if they feel ill. The right kind of thermometer will help you determine if it’s time to call the doctor or go to the emergency room.
Your first aid kit is not complete without a baby thermometer, so be sure to pick one up before you little bundle of joy arrives. It is one of the most important items on your baby product list.
Frequently Asked Questions About Baby Thermometers
Can a baby thermometer be used for adults?
Yes, you can use a baby thermometer on yourself or another adult. A digital thermometer can record temperatures from ear, forehead, armpit mouth or rectum and the temperature is not affected by the size of the person it is being used on. A digital thermometer can be used for newborns, infants, children, adults and sometimes even objects.
What baby thermometer should I buy?
How to clean baby thermometer
Make sure you clean the thermometer before and after each use. Let’s get more in-depth though and go into how to clean different types of baby thermometers.
- Digital Thermometers: Digital thermometers should be rubbed down with rubbing alcohol and left to dry. Choose at least 60 percent rubbing alcohol as this is the most effective in killing bacteria. You can also use a bleach wipe to clean a digital thermometer. Be sure to rinse the thermometer in cool running water when it’s dried up to remove traces of it before using it on your little one. Dry with a microfibre cloth or paper towel before storing or using it.
- Rectal Thermometer: Cleaning a rectal thermometer is easy too. Just use rubbing alcohol or soap and water on the metal part of the thermometer, making sure not to submerge the reader in any sort of liquid. After it is washed up, dry it off with a cloth. Do not use a rectal thermometer orally if it’s been used in the rectum even once.
- Infrared or Forehead Thermometers: These thermometers use only the sensor on the forehead for measuring temperature and thus the only part you need to worry about cleaning is the sensor head. A cotton ball soaked in rubbing alcohol will do the trick. Let the thermometer dry off before putting it away or using it.
- Ear Thermometers: With ear thermometers, you’ll want to avoid submerging the entire monitor in water. Simply rub down the tip that goes into the ear with a cotton ball and rubbing alcohol or hot soapy water. Dry it off with a cloth before storing or using it.
Which baby thermometer is most accurate?
For infants, a rectal thermometer is the most accurate. While it is also the most uncomfortable one to use, it simply takes temperature the best.
Can I check bath water temperature with a baby thermometer?
You shouldn’t use a baby thermometer to check your bath water temperature as there are special bath water thermometers available for this sort of thing. If you do not have a bath water thermometer, you can simply use your elbow to ensure the water is not too hot or too cold for your infant.
Can a baby thermometer tell me the temperature of the room?
A baby thermometer is designed to take the temperature of a body and not the room. If you have a video baby monitor, there may be a room temperature gauge on yours.
Is there a baby thermometer that comes with an app?
Yes, the Kinsa Smart Thermometer for Fever is a thermometer that uses Bluetooth and a cell phone app to help you track and monitor your baby’s fever. It can be used for newborns and adults so it’s pretty good for the whole family. It only takes 8 seconds to read temperature which is amazing if you have a fussy fevering baby.
