Identifying nappy rash

Nappy rash can develop quickly and appears in the area under the nappy. There are common symptoms, though the rash itself can look different from baby to baby.

Have a look under your baby’s nappy. If nappy rash exists, you’ll see some or all of these symptoms:

  • Pinkness or redness over a small or large area of the baby’s bottom, or wherever the nappy touches their skin
  • Dry, raised bumps (called papules)
  • Fluid-filled raised bumps (called pustules)
  • Dryness, peeling or scaling of the skin
  • Swelling
  • The affected area may be warm to touch

Most nappy rashes are mild and can be treated with a simple skincare routine. Your baby will usually feel no pain or discomfort. However, in severe cases and when infection is involved, the condition can be distressing and requires medical treatment. For more information, visit the NHS Choices website.

We recommend you contact your GP in these situations:

  • Your baby cries in pain when the nappy rash is touched
  • Your baby has a fever
  • The nappy rash blisters or starts to bleed
  • The rash spreads to other parts of the baby’s body, like their arms or face
  • The rash does not improve after a week, or stops then reoccurs.
