Childhood Illnesses

How to Manage a Temperature

When babies and children are poorly they often have a high temperature (sometimes called a fever).

A normal temperature in babies and children is around 36.4°C but this can vary from child to child. A high temperature is 38°C or above.

Try to get your child to drink lots of fluids, offer breastfeeds more often if you are breast feeding.
Check on your child often during the night.
Dress your baby or young child in their normal clothing or nightwear whilst they are feeling poorly.

This will be the most comfortable for them. Being either undressed or wrapped up in blankets can make babies and young children feel too cold or too hot, and they may not be able to tell you this.

A temperature is usually a sign that your baby or child has an infection. There are two types of infection your child might get.

A viral infection is most common and your child will usually get better without needing any medicine, such as antibiotics.
A bacterial infection is less common but it is very important that you watch your child for signs that mean they need a to see a nurse or doctor.

If you are worried, you can use this guide to help you identify if you need to get further help, and where to go.

Using a Thermometer

The best thermometer to use to check your child's temperature is a digital one to get a fast and correct reading.

Strip thermometers used on foreheads are not as accurate as digital ones and ear thermometers can be tricky to use.

How to take your child's temperature using a digital thermometer.
- Place the thermometer under their armpit.
- Leave it there for at least 15 seconds (the thermometer may beep when the temperature has been taken).
Possible False Readings

Make sure you do not take a temperature if your child has been wrapped up warmly, the room is very warm, they have just had a bath or they have been very active. These may give a false reading.
If you don't have a thermometer, the signs that your child my have a high temperature are;
- They may feel hotter to touch than usual on their forehead, back or tummy.
- They may be sweaty or clammy.
- They may have red cheeks.
Don’t check your child's hands or feet. These can feel cold even if they have a high temperature.
