A high temperature is very common in young children. The temperature usually returns to normal within 3 or 4 days.
What is a high temperature?
A high temperature is the body's natural response to fighting infections like coughs and colds.
Many things can cause a high temperature in children, from common childhood illnesses like chickenpox and tonsillitis, to vaccinations.
Your child might:
- feel hotter than usual to the touch on their forehead, back or tummy
- feel sweaty or clammy
- have red cheeks
Use a digital thermometer, which you can buy from pharmacies and supermarkets, to take your child's temperature.How to take your child's temperature
- Place the thermometer inside the top of the armpit.
- Gently close the arm over the thermometer and keep it pressed to the side of the body.
- Leave the thermometer in place for as long it says in the instruction leaflet. Some digital thermometers beep when they're ready.
- Remove the thermometer. The display will show your child's temperature.
If your child's just had a bath or been wrapped tightly in a blanket, wait a few minutes then try again.
You can usually look after your child or baby at home. The temperature should go down over 3 or 4 days.
