.
A normal temperature is between 36 and 37.4 degrees Celsius.
In children, any temperature of 38 degrees Celsius or above is considered high. High temperature is common in young children. Their temperature usually returns to normal in 3 or 4 days.
A temperature above 38 degrees Celsius is usually a sign of an infection such as a cold. But it can also be due to more serious infections, so it's important to look at all your child's symptoms.
Symptoms of a high temperature in children
High temperatures are usually caused by minor illnesses. But they can be a sign of serious infections. It's important to check that your child is alert and responding to you.
There is a low risk of serious illness if your child:
is content and smiling
stays awake
is taking drinks
is responding normally to people
There is a high risk of serious illness if your child:
cannot be woken up or if woken, does not stay awake
has a weak or high-pitched continuous cry
has pale or blotchy skin
keeps vomiting
is grunting (making short, low sounds) if they are a baby, or breathing very fast
Some of these symptoms could be signs of sepsis.
Signs of sepsis in children
Urgent advice:
Get medical help immediately if:
you are worried that your child may be seriously ill, even if they do not have a high temperature
Your child can still be sick without a high temperature.
Checking a temperature
If your child has a high temperature they might:
feel hotter than usual to touch - on their forehead, back or tummy
feel sweaty or clammy
have a flushed (reddish) appearance
How to check a child's temperature
Digital thermometers
The best way to check your child's temperature is with a digital thermometer.
You can buy a digital thermometer at a pharmacy, supermarket or online. The thermometer will come with instructions.
Do not take your child's temperature immediately after a bath or when they're wrapped in warm clothing. You will not get an accurate result.
Treatment for a child with a fever
It's rare for a fever to be a sign of anything serious.
You can usually look after your child or baby at home. The temperature should go down over 3 or 4 days.
Do
dress your child in light cotton clothes such as pyjamas - do not underdress them or overwrap them in clothes
give your child plenty of fluids
give your child food if they want it
check on your child regularly during the night
Don't
do not use a cool cloth or sponge to get their temperature down
Medicines to treat a fever
Use either paracetamol or ibuprofen to reduce your child's temperature and to relieve any pain. Talk to your pharmacist for advice.
Important
Never give aspirin to a child under age 16, unless their GP prescribes it. Aspirin can be linked to Reye's syndrome in children. This is a very rare condition that affects the brain and liver.
Start by giving your child either paracetamol or ibuprofen. If the one you started with does not fully reduce their symptoms, try giving them the other.
Make sure to leave:
4 to 6 hours between each dose of paracetamol
6 to 8 hours between each dose of ibuprofen
Do not give more than the recommended dose for your child’s weight.
You can give your child paracetamol and ibuprofen if they are on an antibiotic. An antibiotic will not reduce a fever or relieve pain.
If your child is taking any other prescribed medicine, check with their GP if it's OK to continue taking it.
