Every parent needs to have a thermometer in your medicine cabinet. A thermometer isn’t a want; it is a true need! While you could buy any thermometer, there are some that are better than others. It is easier, with infants, to purchase a thermometer that is meant for babies. There are some that are more accurate than others!

Types of Baby Thermometers

When you search in the stores, there are a variety of types of thermometer. Let’s take a look at the different types and how they compare.

  • Rectal Thermometers: If you are like me, you immediately cringe at the idea of using a rectal thermometer. It is, by far, the most accurate way to take your child’s temperature. However, the process is uncomfortable for your baby and you. Rectal thermometers are a great purchase, especially as his fever starts to creep upwards. When you buy this type of thermometer, a flexible tip and a wide base are the two most important features. The flexible tip makes it gentler on your child, and the wide base ensures you don’t insert it too far, which is dangerous.
  • Temporal Artery Thermometers: The newest thermometer on the market are forehead, or temporal artery, thermometers. You will notice they are more expensive than other choices, but the convenience is worth the cost. Using infrared technology, you move the thermometer across your child’s forehead, scanning and measuring your child’s temperature.

Convenience is the key reason to purchase a temporal artery thermometer. You don’t have to touch your child’s head, so you can use it while they snooze, a vital key to healing. Forehead thermometers are the safest option as well. Chances are you noticed them in hospitals and doctors’ offices. At one time, they were only used for children older than three months old, but there are ones for younger babies.

Also, the temperature variations of the room you are in could give you an inaccurate reading. If you are moving from room to room with a noticeable temperature difference, give the thermometer time to adjust. Some parents also have trouble learning how to use these appropriately. Many people forget to take off the cap and can’t understand why it won’t work properly!

  • Ear Canal Thermometers: If you want another choice for a non-invasive thermometer, thermometers placed into the ear are easy to use and won’t disturb your baby. Ideally, you would opt to use these for kids over 12 months old because their ear canals aren’t wide enough. If they aren’t put in the right spot inside of the ear canal, the reading won’t be as accurate. It is a great purchase for older infants and toddlers!
  • Armpit Thermometer: While taking your child’s temperature under their armpit is considered the least accurate method, it is also the least invasive method. These are not the best choice, but they are cheap.
  • Oral Thermometers: Everyone has memories of sitting with a thermometer in their mouth waiting for the timer to be finished, especially with hopes of ditching school for the day. Oral thermometers are easy to use, safe, and accurate. However, you can’t use them for babies. It is best to wait until your child is three or four years old before giving them a try to ensure an accurate reading.
  • Pacifier Thermometer: On the store shelves, you might notice an attract style of thermometers – a pacifier. In theory, it seems like a fantastic idea. However, they are known for giving inaccurate readings and not recommended by pediatricians. Even though your child might love a pacifier, you are unlike to get the right temperature, defeating the entire process of taking his temperature.

What is the Best Baby Thermometer for You?

There are a few things to consider before deciding the perfect thermometer for your child.

  • Where you want to measure the temperature
  • Age of your child
  • Cooperation level – individual based on your child’s energy level and personality

Besides oral thermometers, you can use most of them for any age group, but doctors do recommend using a rectal thermometer if your child is under the age of six months old.

  • Age 0 to 2 years old: preferred option is rectal reading, then an auxiliary reading. Most pediatricians recommend a rectal thermometer for infants because of its accuracy level. It is crucial that you get an accurate temperature reading to ensure your child is fine. Infants can have seizures easier than older kids when a fever reaches too high. A second choice would be a forehead thermometer because it is still accurate. If you want to use this for your primary option, keep a rectal thermometer on hand so you can double check accuracy.

  • Age 2 to 5 years old: preferred option is rectal reading, then tympanic reading, finally an auxiliary reading. Chances are you won’t convince your five-year-old to allow you to use a rectal thermometer. A temporal artery thermometer is recommended for this age if you can learn how to use it correctly. They are used in hospitals, so you can be sure that they are trustworthy. Always read the instructions!

It isn’t as difficult as it might seem. First, put it in the center of your child’s forehead. Push the button and swipe it across your temple. If it is working correctly, you will hear a beep, letting you know that the reading is accurate.

  • Ages 5 and up: preferred option is oral readings, then a tympanic reading, and finally an auxiliary reading. For older children, an oral thermometer gives the most accurate reading. You could opt for a forehead thermometer or ear canal as well! The great thing about taking the temperature of an older child is that almost all methods deliver accuracy. You could even opt for an armpit reading, so long as you add one degree to the measurement.

Note about Mercury

As you search your grandmother’s medicine cabinet, there is a chance you will stumble upon an older mercury thermometer. These were very common for decades, but now we know that they should be avoided. If the thermometer breaks, the mercury can vaporize, creating toxic fumes in the air around your child. You won’t find them in the stores because doctors have advised against them for years. If you find one, side with caution and toss it out!

Cleaning a Child’s Thermometer

You might have one child or several. No matter how many you have, you are going to need to clean your thermometer after each use. It is best to take a few seconds after each use, especially if you are using a rectal or oral thermometer. Make sure to read directions because some digital and electronic thermometers may not be able to be immersed in water.

  • Soap and Water – The most common way to clean up a thermometer is with simple soap and water. You can wash the tip with soap and water if it comes in contact with your child’s mouth, ear, armpit, and rectum.
  • Alcohol – Keep a box of alcohol wipes in your medicine cabinet. 70% isopropyl alcohol is perfect; just wipe it down. Remember to rinse it off before putting in your child’s mouth, or you could rinse and dry it before putting it away!

When to Seek Medical Treatment

Parents need to know when to seek help from a doctor. A fever isn’t necessarily a bad thing, and it doesn’t always need treatment. However, it is better to be safe than to miss a problem and suffer worse consequences. Here is what to look for before making a phone call.

  • A forehead, ear or rectal temperature that is higher than 100.4 F.
  • An oral temperature is higher than 100 F.
  • An armpit temperature is higher than 99 F. Remember, armpit temperatures are inaccurate. You should have another choice to confirm a high temperature.

The best baby thermometer is that one that performs all of the functions necessary for your family quickly and accurately. You have to consider the factors of your individual family. The age of your child is the most important; infants require different considerations. You also want to think about how many children you have and the easiest way to take temperatures in your home. Using these qualifications help to narrow down the process, sooner rather than later because the purchase of a thermometer is a necessity.
