Most infants develop a rash in the nappy area at some time during the first 12 months. It usually responds well to some simple rules.

Nappy rash produces red patches and sometimes sores or ulcers on the skin. It is usually due to moisture, friction and irritation from urine and faeces.

How to treat nappy rash

• Use good quality disposable nappies wherever possible. They keep the skin drier than cloth nappies. 
• Avoid plastic overpants and nappy liners. 
• Change nappies as soon as wet or soiled, especially cloth nappies. 
• Keep the nappy off when possible.
• Do not use soap, baby wipes or bubble baths on your baby's delicate skin. Use water or aqueous cream for cleaning.
• Apply a simple emollient at every change e.g. zinc/castor oil, aqueous cream.

If the rash is not settling, see your doctor. More severe cases may require 1% hydrocortisone cream (script only). This is very safe for short term use.

Nappy rashes often become infected with a yeast called candida albicans (thrush). This causes small red spots and pimples and is treated with an antifungal cream e.g. nystatin or clotrimazole.

A number of other skin disorders and infections also occur in the nappy area and may need special treatment.
