Taking your child’s temperature

If your child seems unwell, it’s important to know how to take his temperature so you can check whether he has a fever. This guide explains how to take a child’s temperature using different kinds of thermometers.

When to take your child’s temperature

You might want to take your child’s temperature if your child is:

  • unwell and feels warmer than usual
  • irritable and crying
  • more sleepy than usual
  • in pain
  • refusing to drink, or vomiting.
Your child’s average body temperature is about 37°C. If your child’s temperature is higher than 38°C, she probably has a fever.

Types of thermometers

It’s best to check your child’s temperature using a thermometer. Feeling your child’s skin temperature by putting your hand to his forehead isn’t a reliable way of diagnosing a fever.

Most modern thermometers are digital thermometers.

Digital probe thermometers
Digital probe thermometers are the most basic and common types of thermometers.

You can use a digital probe thermometer to take your child’s temperature in two main ways:

  • Orally – you put the thermometer in your child’s mouth under the tongue.
  • Axillary – you put the thermometer under your child’s armpit.

Oral temperature readings are usually the most accurate from digital probe thermometers.

If you plan to check your child’s temperature orally and under her armpit, make sure to clean the thermometer well between each use. You can clean a thermometer using warm soapy water or an alcohol wipe.

Although you can use a digital probe thermometer to take a rectal temperature reading, this isn’t recommended. There’s a risk that the tip of the thermometer could damage the lining of your child’s rectum.

Digital ear thermometers 
Digital ear thermometers are specially designed for use in children’s ears. Ear thermometers are quick and easy to use, but they can be a little inaccurate.

Digital temporal artery thermometers
Digital temporal artery thermometers use infrared scanning to measure the temperature on your child’s forehead. These are the simplest types of thermometers to use, and they’re also one of the most accurate.

An advantage of these thermometers is that you can check a sleeping child without waking him.

You can also use these types of thermometers to check the temperature of bath water.

Digital pacifier thermometers and fever strips aren’t recommended because they’re not very accurate. Mercury thermometers can poison a child if they break. If you’re using a mercury thermometer, consider replacing it with one of the types of digital thermometers above.

Taking your child’s temperature

No matter what kind of thermometer you have, it’s important to carefully read the instructions that come with it before using it for the first time.

Here are more tips to help you take your child’s temperature accurately.

Oral temperatures
You take an oral temperature using a probe thermometer:

  • Wait five minutes after your child has had a hot or cold drink.
  • Place the thermometer well under one side of your child’s tongue.
  • Have your child hold it in place with her lips, not her teeth, and tell her to breathe through her nose.
  • Wait until the thermometer beeps and then check the digital display for the temperature reading.

Add 0.5°C to your child’s oral readings to estimate his true body temperature.

If your child has a blocked nose because of a cold, she might find it hard to breathe with her mouth closed.

You can take oral temperatures in children over four years. It’s hard to take an oral temperature in children younger than this, because they can’t always co-operate with you.

Armpit temperatures
You take an armpit temperature using a probe thermometer:

  • Place the thermometer in your child’s armpit.
  • Close your child’s arm over the thermometer, holding his elbow against his body.
  • Wait until the thermometer beeps and then check the digital display for the temperature reading.

Taking your child’s temperature under the armpit is usually the easiest way to do it, especially in young children. Unfortunately, it’s also the least accurate method.

Add 1°C to your child’s armpit readings to estimate her true body temperature.

Ear temperatures
You take an ear temperature using an ear thermometer:

  • Put a plastic cover over the tip of the thermometer.
  • Put the tip gently just inside your child’s ear canal.
  • Wait until the thermometer beeps and then check the digital display for the temperature reading.

If you use a digital ear thermometer correctly, it’s accurate to within about 1°C, as long as your child’s ear canal isn’t too small or doesn’t have too much wax in it.

Forehead or temporal artery temperatures
You take a forehead temperature using a temporal artery thermometer:

  • Check that your child’s forehead is dry before starting.
  • Gently scan the thermometer across your child’s forehead.
  • Remove the thermometer and then check the digital display for the temperature reading.

Temporal artery temperature readings are usually the most accurate.
