The Best Baby Thermometer: Our Picks

Guide: Questions you should ask yourself before buying a baby thermometer

Why do I need a baby thermometer?

A baby thermometer is a thermometer specially designed for babies to give accurate body temperature readings. Babies can quickly get a high temperature or fever, so it is useful to keep a close eye on their temperature.

If the fever is high, you should consult a doctor, otherwise there may be risks.

What do I have to consider?

Before buying a baby thermometer, you should think about what you want to use it for. In addition to taking the temperature, it can also be used as a night light, for example. If your baby often has a fever and gets sick quickly, you should also find out in advance about the quality of the baby thermometer and its function.

Your baby may also react sensitively to the tip of the baby thermometer. In this case, you should buy an infrared baby thermometer because it measures without contact. It is also important to check in advance what age the baby thermometer is suitable for.

What are the options for taking a baby's temperature?

You can take the temperature in the bottom, under the armpits, in the mouth, on the forehead or in the ear. The measurement in the bottom, i.e. rectally, is considered the most accurate option, as it corresponds most closely to the core body temperature.

You should use a cream or Vaseline with this method so that it does not hurt the baby. However, many babies or toddlers do not like this method and cannot hold still. If this is the case, you should choose another method.

But you should also refrain from using the mouth measurement in this case, because the baby might chew on the baby thermometer or move it too much.

How much does a baby thermometer cost?

The price range of baby thermometers is between 2-1300 Euros. Prices vary depending on the brand, type, design and function. Simple analogue baby thermometers are often cheaper than digital baby thermometers because they have more functions. The most expensive are the infrared baby thermometers.

Type Price range
Analogue baby thermometer 8-10 euros
Digital baby thermometer 2-60 euros
Infrared baby thermometer 3-1300 euros

What is an alternative to a baby thermometer?

An alternative to the baby thermometer would be the normal clinical thermometer for adults or taking a temperature by hand.

Clinical thermometer for adults

A clinical thermometer for adults has the same function as a baby thermometer. However, baby thermometers are made especially for babies and have a different shape and sometimes different functions that are specifically designed for babies.

However, most adult clinical thermometers can also be used for babies or infants.

Taking a temperature by hand

You cannot tell the exact temperature of your baby without a thermometer. If anything, you can test whether your baby has an elevated temperature or a really high fever.

If your baby feels hot, sweaty and has red cheeks, then it is probably a fever. Another indicator can be cold hands, feet and sweating. Loss of appetite and aching limbs can also be signs of fever.

Decision: What types of baby thermometers are there and which one is right for me?

If you want to get a baby thermometer, there are three alternatives you can choose between

  • Analogue baby thermometer
  • Digital baby thermometer
  • Infrared baby thermometer

Each of them has its advantages and disadvantages. Depending on what you prefer and what you want to use the baby thermometer for, a different type is suitable for you. In the following section, we would like to make the decision easier for you.

What are the features of an analogue baby thermometer and what are the advantages and disadvantages?

Analogue baby thermometers have been around the longest and are the best known. They are made of glass and have a liquid inside. In the past, this liquid consisted of mercury, but these are banned nowadays because the leakage of the mercury liquid poses too high a risk.

However, the current liquid, called Galistan, is safe. The baby thermometer has a measuring scale on which the temperature is displayed. You can use the Analogue Baby Thermometer in the armpits, mouth and rectal area.

Advantages
  • Long life
  • Works without batteries
  • Environmentally friendly
Disadvantages
  • Fragile
  • Longer measuring time
  • Not flexible

The advantage is that no batteries need to be used with this variant and this baby thermometer has a long lifespan.

The disadvantage is that you have to measure for a relatively long time. Rectally you need about 3-5 minutes and in the armpits about 10 minutes to get an accurate result.

The baby thermometer is also made of glass and therefore fragile. Accordingly, you have to be careful not to drop it or crush it. This can be very dangerous for babies, as their reaction is unpredictable.

What are the characteristics of a digital baby thermometer and what are the advantages and disadvantages?

Digital baby thermometers are made of plastic and have an oval shape. The measuring tip of this variant can be flexible or fixed.

The advantage of the flexible shape is that it is easier to insert. Another advantage is that the temperature is shown on the display. In addition, a signal tone sounds when the measurement is finished.

Advantages
  • Easy handling
  • shorter measuring time
  • waterproof
  • disyplay display
Disadvantages
  • Use with batteries

You also don't have to allow as much time to take a reading because it takes less time than the analogue version. Most clinical thermometers of this type are waterproof, have a long runtime and are easy to use.

The disadvantage is that you need batteries for this baby thermometer. If they are empty or you don't have any at home, you can't take the temperature. Changing the batteries can also be more complicated with some thermometers.

What are the advantages and disadvantages of an infrared baby thermometer?

The advantage of this variant is that the measurement is completed within a few seconds and you get the temperature displayed.

The measurement does not have to be taken rectally, but can be taken on the forehead or ears. But contactless measurement is also possible.

Advantages
  • Easy to use
  • Fast measurement
  • Non-contact
Disadvantages
  • Inaccurate measurement results
  • Shape impractical

The disadvantage can be that the values are inaccurate and may differ from each other. Therefore, it is sometimes necessary to repeat the measurement. The analogue baby thermometers also often have a larger and wider shape than the other thermometers and can therefore be more impractical if you want to take them with you on the go, for example.

Buying criteria: Use these factors to compare and evaluate baby thermometers for children

In the following, we would like to show you which factors you can use to compare and evaluate baby thermometers. This will make it easier for you to decide whether a particular baby thermometer is suitable for you or not.

In summary, these are:

  • Measuring tip
  • Multifunctionality
  • Night light
  • Waterproof
  • Age recommendation

Measuring tip

A pre-warmed and flexible measuring tip can be very comfortable for the baby. It is not immediately frightened, as is the case with cold tips. This can mean that the baby does not fidget or become restless. Furthermore, the pre-warmed measuring tip can produce accurate measurement results.

Multifunctionality

The multifunctionality of baby thermometers refers to the way they are used, i.e. rectally, on the ears, in the mouth or under the armpits. Some baby thermometers can only give accurate readings rectally and others can be used in all variations.

The advantage of this is that it benefits the baby. Because sometimes the baby has a phase in which it may not like rectal measurement and you can then measure under the armpits.

Night light

Some baby thermometers have an integrated light function. This means that you can take your baby's temperature in the dark or leave a light on in the room.

When your baby is asleep, the light will not wake him or her up, making it easier to take the temperature.

Waterproof

The baby thermometers are also waterproof and can be used in the bath. Your baby is relaxed and the introduction and handling can be easier.

But even if your baby thermometer should fly into the sink, it won't break and can still be used.

Age recommendation

The recommended age of the baby thermometer is very important. You should find out in advance whether the baby thermometer is suitable for all ages or whether it is only suitable for babies from a few months.

Facts worth knowing about baby thermometers

What do the temperatures on the baby thermometer tell you?

The normal temperature of a human being is between 36.3-37.4 degrees. Elevated temperature is said to be 37.5-38 degrees. If your baby's temperature is in the range of 38.1-38.5 degrees, then he or she has a slight temperature.

A fever exists at 38.6-39 degrees and a high fever at 39.1-39.9 degrees. If your baby thermometer shows a value of 40 degrees or more, then your baby has a very high fever.

If you have a high or very high fever of 40 degrees or more, you should see a doctor immediately.

If the temperature is mild and the fever is normal, you should take the temperature regularly and contact a doctor if there is no improvement.

What can I do if my child has a fever?

It is very important that your baby drinks enough fluids when he or she has a fever, otherwise the loss of fluids can cause dehydration. Suitable, easily digestible food is also important to help your baby regain its strength.

Your baby should get enough sleep and rest so that the body can rest and regenerate. It is also advisable to change the bed linen regularly, as it can become damp from sweating.

If there is no improvement in your baby's health and temperature, you should definitely consult a doctor.

Sleep is very important for your baby. Especially if your baby is sick and has a fever, you should make sure he or she gets enough rest and sleep. But your physical warmth is also important for recovery. This makes your baby feel that you are there and that he or she can relax and is not alone. (Image source: Unsplash.com / Brytny)

How do I clean a baby thermometer?

You can find the cleaning instructions in the user manual of your baby thermometer, they are very important regarding hygiene. If you do not clean the baby thermometer properly, existing bacteria in the rectal area can spread and cause further illnesses.

You can buy special cleaning products for baby thermometers. However, if you are unsure, you can simply ask the manufacturer or the pharmacy.
