Guide to purchasing the best baby thermometer

Some people do not need any device to assess the body temperature of their babies because they can use the “touch test” effectively. The quick test provides a fast estimation of the body temperature but it does not provide a true fever severity measure. To get the real temperature reading, you will require a good baby thermometer. A baby thermometer should consistently monitor the temperature of your baby because even the slightest change can indicate a serious illness or infection. Here are some of the factors to consider when shopping for a baby thermometer.


Most thermometers in the market today are purposely designed for infants and babies, but you will also get some designed for older children aged between 3 and 5 years. When buying one for ages below 3 years, you should avoid the oral versions. Rectal thermometers are ideal for kids of all ages because they are easy to use and accurate. However, children above four years will complain about discomfort. Oral thermometers will be a good choice for such children.


As we have stated, a slight body temperature change can indicate a serious issue. Therefore, the baby thermometer should not only be easy to use but it should also be accurate. Inaccurate thermometers are known to cause unnecessary stress and anxiety for parents. After getting the appropriate thermometer for your baby’s age, consider the accuracy.


No one would want to hurt his/her baby when checking the body temperature. Therefore, the safety and design of the thermometer are important. A baby thermometer designed to go into the mouth, rectal or ear requires proper insertion into the body part. After buying any of the types, consult your user manual to be sure that you are getting accurate readings. Safety is important. Remember to clean the thermometer after each use. Again, do not use the thermometer immediately after a hot bath because it will take almost one hour for your baby’s body temperature to stabilize.


Most baby thermometers are affordable and that is the reason you should always have one. Nothing will look as bad as rushing to an ER or doctor’s room in a panic state only to realize that the temperature level is not as bad as you had assumed through your “touch test”. Do your research when buying a thermometer and consider our top ten selections.

Response time

Any thermometer offering fast readouts is a good choice for your baby. As a parent, you should know that it is hard to keep your baby still for a long time when checking the temperature. Infrared baby thermometers are known to provide the fastest results but they are more expensive.


High-quality baby thermometers come with several helpful extras. Go for a baby thermometer featuring a large and backlit display for easier temperature reading. Moreover, a thermometer with a fever alert that rings when the temperature is very high will be more helpful. You can buy several baby thermometers and place them in different body parts to be sure that the readings you are getting are the right ones.

Types of baby thermometers

The market provides various types of baby thermometers and you will always find one to match your needs. Your selection will highly depend on the features you need on the thermometer. Any readings above 100.4 degrees Fahrenheit are a serious issue that will need urgent attention. Here are a few types of reliable thermometers in the market today.

Ear canal thermometers

When choosing a baby thermometer you should think about the ease of use and preciseness. Ear canal baby thermometers are non-invasive and easy to use. They are also appropriate for babies above 12 months old because babies below that age do not have an ear canal large enough to allow the recording of temperature measurements accurately. The placement of the thermometer is important.

Pacifier thermometers

Pacifier baby thermometers are ideal for young babies but they will not produce accurate results. If possible, you will need to try the other available alternatives.

Axillary/armpit thermometers

Unfortunately, axillary thermometers, also known as armpit thermometers, are the least accurate. Even though you will have something to rely upon, you should buy a better baby thermometer.

Baby thermometer safety

Even though the safety of baby thermometers relates to the criteria you opt for when selecting one, the modern-day thermometers are safer than they used to be in the past. Most thermometers are digital and therefore the risks of touching or ingesting dangerous chemicals are very low. That makes them safer to use. Nevertheless, as a parent, you have to know all the associated dangers and flaws. It is also important you clean your baby thermometer after every use. Remember to read the instructions that come with the product so that you can always get accurate readings.

Glass thermometers

This is the first type of baby thermometers you would want to avoid. The thermometers contain mercury and as you might be aware that mercury is extremely poisonous. Glass is delicate and the delicate substance might crack and shatter, posing a big threat to your baby. Glass thermometers are among the old-school methods that people should replace for good.

Pacifier thermometers

Pacifier thermometers are the other type to avoid for the safety of your baby. The temperature measurement can take between 3-5 minutes, which is a long time. However, the worst thing is that they lack accuracy and pose a choking hazard.

Oral thermometers

Oral thermometers are a good choice for older kids – above four years. However, you should avoid them when shopping for a thermometer to take the temperature of your babies below that age. Older children will sit still and will not try to swallow the thermometer.

How To Use A Baby Thermometer

Do not panic when the display on your baby thermometer starts to skyrocket. Read the manual to know how long it will take the display to stabilize. Some baby thermometers will require you to wait for at least two minutes so that they can return to the normal temperature. Here are the tips you need to observe when using a thermometer to be sure that you are recording the right readings.

Using a rectal thermometer

Insert the rectal thermometer around a half-inch or one inch into the rectum of your baby – not between the cheeks – and wait for it to beep. You can use some lubricant for smooth reading or have someone to distract the baby.

Using underarm thermometers

When using an underarm thermometer, unclothe the baby on one arm. Place the thermometer higher into the armpit. Hold it in place so that the reading can be complete. Ensure that only the skin is touching the tip of your thermometer.

Using temporal artery thermometers

Place the thermometer on the forehead – between the eyes. Press the button if the baby is still and wait for a few seconds. When reading, the device should not be necessarily in contact with the skin of your baby.

Using oral thermometers

Position your baby thermometer under the tongue of your child and ask him/her to hold the mouth closed for the reading to end. The device should not touch the skin.

Using ear thermometers

Stabilize the head of your baby and start pulling the ear upwards and backward. That way, you will open the ear canal. Insert the tip of your device and ensure that it is touching the child’s ear evenly. The tip should be straight and pointing down or up. Press the button and wait for it to beep. Remove it and use a cotton swab along with some alcohol to sanitize the thermometer.

Ear and oral readings are ideal for children between 1 and 3 years, while axillary and rectal readings are suitable for younger babies or new-borns. Buy two or more types of thermometers so that you can always confirm the reading. Whenever you get two different temperature readings, use the average. Avoid taking several readings because even the accurate devices might have variations.

Frequently Asked Questions

Q: What is the normal body temperature?
A: The normal body temperature is 98.6 degrees Fahrenheit but that will highly depend on how you record the temperature and the age of the person, the time of the day and what the person has been doing. Generally, a body temperature above 100.4 degrees Fahrenheit is considered a fever. When taking the temperature with an armpit thermometer, know that anything above 99.3 degrees Fahrenheit indicates a fever.

Q: Which is the best type of baby thermometer to use?
A: No type of thermometer is perfect – you have to base your selections on your requirements. When searching for an affordable and simple thermometer, go for digital stick thermometers. Non-contact thermometers are ideal for people who want to take the readings of their baby’s body temperature without waking them up. When buying a thermometer, keep your goals in mind.

Q: How should I use a baby thermometer?
A: Each model and type of baby thermometer works uniquely. So, read the user manual and familiarize yourself with all instructions before using a new thermometer.

Q: Are forehead thermometers accurate?
A: Forehead thermometers provide readings that are roughly a half or one degree lower than the oral thermometers provide. But because they provide the measurement of heat in the temporal artery in your baby’s forehead, they are the most accurate. Most medical professionals opt for them.

Q: Should I sanitize forehead thermometers?
A: Even though a forehead thermometer will only get into contact with the baby’s forehead, the forehead skin might have germs. To eliminate the chances of passing the germs between your family members, you should wipe down the sensor or probe area of the thermometer with some alcohol after each use. When using non-contact models, you will also need to clean the probe to avoid passing germs in case of accidental contact with the baby’s skin.

Q: Which batteries should I use for my forehead thermometer?
A: The type of battery you need for your forehead thermometer will highly depend on the model you are using. However, most forehead thermometers will require two AAA or AA batteries.


Some years ago, the selection of a baby thermometer was very easy. But during those days, Bluetooth capabilities, infrared technology, wearable thermometers and smart technologies were inexistent. Now, the process can be overwhelming and daunting due to the many options that the market offers. That is the reason we have taken our time to prepare the list of top baby thermometers in the market today and the buying guide. With this guide, you will easily find a state-of-the-art thermometer to match your needs.
