Rashes in babies and children

Many things can cause a rash in children and they’re often nothing to worry about.

Call 999 or go to A&E if your child has a rash and they:

  • have a stiff neck
  • are bothered by light
  • seem confused
  • are shaking uncontrollably
  • have a fever you can’t control
  • has unusually cold hands and feet
  • have a rash that doesn’t fade when you press a glass against it

These can be signs of meningitis.

See your GP

If your child seems unwell with a rash and has a fever.

The information below shouldn’t be used to self-diagnose your child’s condition, but it should give you a better idea of what is causing the rash.

Rash with fever

Fever and red cheeks

It usually clears up within a week. Children’s paracetamol can bring down a fever.

Small spots and blisters
