How To Choose A Baby Thermometer – Buying Guide

When it comes time to buy a baby thermometer for your little one, going to the store and buying the first one you see isn’t the best thing to as thermometers for adults aren’t necessarily the best thing for a baby. When we decided which thermometers to feature on our list, we wanted to choose those that met certain criteria first. Our criteria included:

Age appropriate

When you choose a baby thermometer, you want to make sure that the one you select will work correctly for your child. Certain types will work on a child of any age, but can be recommended for specific age types because they will give the most accurate reading when compared to other options. A rectal thermometer with a flexible tip may be a good idea because they can make your child a bit uncomfortable while being used.

Ease of use

Finding a thermometer that is easy to use is very beneficial when you have a sick baby.  Spending time reading complicated or confusing instructions and struggling to get a thermometer to work and let you know if your baby has a fever isn’t something that many parents have the time or patience for.


Some thermometers can be better than others when it comes to an accurate temperature reading. Some can have limitations when it comes to getting an accurate reading, like pacifier thermometers which can be taken or spit out by the baby while trying to get an accurate reading. Choosing one that will provide you with an accurate reading each and every time is vital.


So you take your baby’s temperature and its accurate, almost every time. This can be very frustrating for a parent who is trying to determine if their child has a fever. A baby thermometer should provide you with an accurate temperature every single time. There are no exceptions to this and not getting consistent readings could cause you to misdiagnose your child, and that could be a very bad thing.


When we were children, the baby thermometers that were used were the ones where the temperature level was gauged by a silver liquid inside a glass tube and could tell your temperature pretty well. That silver liquid though, was mercury. Yes, the same mercury that can be a very dangerous neurotoxin, was used in very easily broken glass thermometers for years. Thankfully, with digital thermometers, that risk is gone, so if you own a mercury thermometer, you should dispose of it to avoid any possible problems.

Response Time

When your child is sick, you want to make sure that you get the information you need right away. Most digital thermometers will display a temperature anywhere between 10 and 80 seconds, depending on the model. Infrared thermometers have the fastest response time at 2 to 3 seconds.

Benefits of a Baby Thermometer

Owning a baby thermometer should be one of the first items that you purchase once you find out that you’re expecting. The benefits that comes from owning a baby thermometer can pay for itself time after time. These benefits include:

Immediate Results

When we used to all use the mercury filled, glass thermometers, sometimes it felt like we would sit there forever waiting for a result. With the baby thermometers on the market today, getting a reading is much quicker than in the past, helping parents determine whether or not their little one has a fever so they can help them feel better faster.


Let’s face facts. It was always tough to tell on the old glass thermometers whether the temperature was 98.6 and 98.8 degrees with those little lines. With a digital baby thermometer, the temperature is displayed much more accurately than in the past. That can make it much easier to determine whether or not you little one is sick.


Checking your baby’s temperature is easy as can be. Many baby thermometers are extremely portable and have no issue being carried in your purse or their diaper bag. Many come with carry cases or even covers to help keep dirt and other messes off of them that might affect their performance.


While this also relates to the criteria you should look for when choosing a baby thermometer, thermometers are much safer now than they had been in the past. With many thermometers being digital, the risk of ingestion or even touching of a dangerous chemical has been dramatically reduced, and in turn making them much safer to use.

Long Lasting

One of the most amazing benefits of a baby thermometer is the long life span that a baby thermometer can have. Obviously, your little one is going to grow up and grow up quickly. But unlike other products that you may buy for your child, a baby thermometer, depending on the model, can be used not only as they get older, but by other members of the family as well. This makes the value of owning a baby thermometer more than worth the price paid.

Different types of Baby Thermometers

On the market today, there are many different variations of thermometers available to parents with little ones. The type you choose can be wholly dependent on what features and needs you have for a thermometer for your child. Those types include:


A multi-use thermometer reads your child’s body temperature with a sensor that is typically located in a small metal tip at one end of the thermometer. This type of thermometer allows a parent to take their child’s temperature orally, rectally or under the arm (axillary).

These tend to be the least expensive thermometers and also the most common. Simple to use, they can give accurate readings when used rectally but require you to disturb them when your child is sleeping or sick to get the reading.


A rectal thermometer consistently gives a parent accurate results of their child’s temperature. These relatively inexpensive thermometers can be found in any drug or grocery store. They can require a bit of waiting to get a reading, which can make a sick or even sleeping child cranky while it’s being used. Some parents have trepidation about using these thermometers because they may injure their child. However, current designs are manufactured to keep that from happening.


Forehead thermometers, also known as temporal-artery thermometers are relatively new on the market and can be on the pricier end of the spectrum. While traditionally used in hospitals, manufacturers have started creating home versions for use with your little one. In the past, it was thought that you little should be at least 3 months of age, but recent research shows that forehead thermometers are perfectly safe to use at any age, but if your child is under 3 months, you may want to confirm the temperature with a rectal thermometer.


Otherwise known as a tympanic thermometer, uses an infrared ray to measure the temperature inside your little one’s ear. A big benefit with this type of thermometer is that they are relatively quick, safe to use and not uncomfortable at all for your child. Getting an accurate reading can be a bit trickier at times because the device needs to be at the correct position to work correctly. These types of thermometers are generally recommended for children 6 months and older.


Generally recommended for children ages 4 and older, an oral thermometer is held under your child’s tongue to achieve a temperature reading. Even though using this type of thermometer is recommended for children of at least 4 years old, ensuring proper use is also very important.


Designed to be used under your child’s arm, axillary thermometers are designed to be easy to use, convenient and safe. While nowhere near as accurate as other thermometers on the market. These types of thermometers can be used with children of any age.


The newest type of thermometer available on the market, these types of thermometers are designed to integrate with your smartphone or tablet. Some include a patch that you can place under your child’s arm to read and transmit their temperature to your phone letting you keep track of their health not only digitally, but wirelessly as well.
