What is a fever?

A normal temperature in babies and children is about 36.4C, but this can vary slightly from child to child.

A fever is a high temperature of 38C or more.

Fever 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.

Symptoms

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

  1. Place the thermometer inside the top of the armpit.
  2. Gently close the arm over the thermometer and keep it pressed to the side of the body.
  3. Leave the thermometer in place for as long it says in the instruction leaflet. Some digital thermometers beep when they're ready.
  4. 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.

Things you can try

You can usually look after your child or baby at home. The temperature should go down over 3 or 4 days.

Do

  • give them plenty of fluids

  • look out for signs of dehydration

  • give them food if they want it

  • check on your child regularly during the night

  • keep them at home

  • give them paracetamol if they're distressed or unwell

  • get medical advice if you're worried about your child

Don't

  • do not undress your child or sponge them down to cool them – fever is a natural and healthy response to infection

  • do not cover them up in too many clothes or bedclothes

  • do not give aspirin to under-16s

  • do not combine ibuprofen and paracetamol, unless a GP tells you to

  • do not give paracetamol to a child under 2 months

  • do not give ibuprofen to a child under 3 months or under 5kg

  • do not give ibuprofen to children with asthma

Knowing the signs of more serious illness

It's quite rare for fever to be a sign of anything serious (like meningitis, a urinary tract infection and sepsis).

Call 999 or go to A&E if your child:

  • has a stiff neck
  • has a rash that does not fade when you press a glass against it
  • is bothered by light
  • has a fit (febrile seizure) for the first time (they cannot stop shaking)
  • has unusually cold hands and feet
  • has pale, blotchy, blue or grey skin
  • has a weak, high-pitched cry that's not like their normal cry
  • is drowsy and hard to wake
  • finds it hard to breathe and sucks their stomach in under their ribs
  • has a soft spot on their head that curves outwards (bulging fontanelle)
