What causes nappy rash?

  • The area under a nappy is a difficult environment for baby skin. A combination of excess moisture, warmth, urine and faeces and friction can all lead to nappy rash.
  • The nappy creates an enclosed area around the bottom - this increases warmth, moisture and encourages the growth of micro-organisms that can cause infection.
  • Chafing, due either to skin rubbing against the nappy, or from skin folds, can damage and irritate the skin.
  • Ongoing contact of the skin with urine, faeces or both, can lead to a formation of ammonia which can irritate baby’s skin.

There is also a common link made between nappy rash and teething, as well as the transition to solid foods.
