Fever in children: what to do and when to worry

A temperature of 38°C or above is a fever. In itself it is not dangerous - how your child looks and behaves matters far more than the number on the thermometer.

Caring for a feverish child at home

  • Offer fluids frequently, in small amounts if your child is reluctant.
  • Dress them normally - do not wrap up or sponge with cold water.
  • Paracetamol or ibuprofen may be used if your child is distressed, not simply to reduce the number.
  • Never give aspirin to a child.
  • Check on them regularly overnight.

Get urgent medical help

Trust your instinct. Parents notice deterioration before any scoring system does, and no clinician will mind you seeking advice.

  • A rash that does not fade when pressed with a glass.
  • Difficulty breathing, grunting, or drawing in beneath the ribs.
  • A baby under 3 months with a temperature of 38°C or above.
  • Unusually drowsy, floppy, or very difficult to wake.
  • A stiff neck, a bulging fontanelle, or a fit or seizure.
  • Cold hands and feet with mottled or blue-tinged skin.
  • Markedly reduced wet nappies or no urine for 8–12 hours.

Fever that will not settle

A fever lasting more than five days, or one that returns after your child appeared to recover, should be reviewed by a doctor. So should any fever in a child who has recently travelled abroad or who has a long-term health condition.
