High temperature (fever) in children

  • High temperature (fever) in children


  • A high temperature is very common in young children. The temperature usually returns to normal within 3 or 4 days.


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


    A high temperature is 38C or more.


    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.



    Checking a high temperature

    Your child might:


    • feel hotter than usual when you touch their back or chest

    • feel sweaty

    • look or feel unwell


    Use a digital thermometer, which you can buy from pharmacies and supermarkets, to take your child's temperature.


    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, a high temperature is a natural and healthy response to infection


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


    • do not give aspirin to children under 16 years of age


    • 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
