What Is The Most Accurate Baby Thermometer?

Having the most accurate baby thermometer on hand is important to measure the temperature when you suspect your baby has a fever.

The number one requirement of a baby thermometer is that it needs to be accurate and consistent. You also do not want a thermometer that gives different readings when you measure several times in a row.

What to look for when buying a baby thermometer?

Some features a good thermometer must have:

  • Easy to use
  • Easy to clean
  • Fast reading
  • To read both Celsius and Fahrenheit

Having said that, it’s not that simple to choose the perfect thermometer for your family. You can use a thermometer (oral, forehead, rectal, under the arm, and multiuse). And this can make it somewhat difficult to find the right one.

First of all, you need to decide who you want to use the thermometer for. Is it for your newborn or an older child, or do you need one that the whole family can use? Different thermometers are used for different age groups, especially for kids.

Different Types Of Baby Thermometers


rectal baby thermometer

To measure your newborn’s temperature, insert a rectal thermometer into the baby’s rectum. Rectal thermometers will give the most accurate reading; most doctors recommend this as the most accurate baby thermometer. This has nothing to do with the thermometer type, but with the part of the body you measure.

For new mothers, it may appear a scary thing to do to insert a thermometer in the baby’s rectum. But believe me, if you do it correctly, your infant will hardly notice it. The newest rectal thermometers have flexible tips, making them safe and painless for the baby.


The temperature measured under the arm is lower than readings taken in the mouth, rectum, or ear. This is because the temperature is measured outside the body. To measure auxiliary is simple, just put the thermometer under your kid’s armpit, and close the arm snugly over the thermometer. Wait for at least 3 to 4 minutes to read the result. With a temperature equal to or higher than. 37.4°C (99.2°F), your child has a fever.


This method is recommended for children of 4 or 5 years of age as the most reliable way of measuring the temperature. It is surely more accurate than taking the temperature in the ear or under the armpit. Make sure you clean the thermometer before use according to the directions.

To measure the temperature, put the end of the thermometer under the tongue, and tell your child to close the lips around it. Wait until you hear the beeper and remove it so you can read the temperature on the screen. Make sure you don’t use an old-fashioned glass thermometer. Accidentally biting them can cause them to break, making them very dangerous.


tympanic thermometer or baby ear thermometer has to be placed in the baby’s ear canal. It uses infrared light to measure the tympanic membrane’s temperature, also known as the eardrum.

Often using an ear thermometer can be hard for a feverish baby. To keep the child sitting still, the time you need to get a correct reading is difficult. You will want a thermometer that reads quickly. If used correctly, the tympanic thermometer can give an accurate reading in as little as 2 seconds.

The plastic strip thermometer contains (thermochromic) liquid crystals. These liquid crystals change color at different temperatures. Put on the baby’s forehead for 15 seconds; a color change will indicate the temperature. These strips are inexpensive and the least accurate making them not the best baby thermometer for a child.

Pacifier thermometers are digital thermometers housed in a silicone pacifier. This method works only with a baby that will keep a pacifier in his mouth for at least 2 to 3 minutes without moving. Before each use, you must check these thermometers, as harmful components may leak from the pacifier if a child bites on it.
