Rashes in babies and children

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

Immediate action required: Call 999 or go to A&E now if:

your child has a rash, is also unwell, and has any of these symptoms:

  • a stiff neck
  • bothered by light
  • seems confused
  • a high temperature
  • their rash does not fade when you press a glass against it (do the glass test from Meningitis Now)
  • difficulty breathing (you may notice grunting noises or their tummy sucking under their ribs), breathlessness, or they're breathing very fast
  • their skin, lips or tongue look pale, blue, grey or blotchy

These can be signs of meningitis.

It can be harder to see a change in skin colour on brown and black skin. Check the soles of the feet, palms, lips, tongue and inside the eyelids for colour changes.

As a parent, you may know if your child seems seriously unwell and should trust your own judgement.
