Nappy rash is a common condition thought to affect up to a third of nappy-wearing babies at any given time.
It causes your baby's skin to become sore and irritated in the area around the nappy, and covered in pink or red spots or blotches.
Nappy rash is usually caused by your baby's skin coming into contact with urine and faeces in their nappy.
The rash usually develops when your baby is between 9 and 12 months old.
How serious is it?
Most nappy rashes are mild and can be treated with a simple skin care routine. Your baby will usually feel no pain or discomfort.
However, some nappy rashes are more severe and can be caused by an underlying condition or bacterial infection. A severe rash is painful and distressing for your baby. It usually requires treatment with medication (see Treatment of nappy rash for more information).
