What causes nappy rash?

Wetness from urine and faeces

Wetness is the main cause of nappy rash. The longer the nappy is wet or dirty the higher the risk.

Thrush

Thrush is an infection which thrives in warm moist areas. It is almost always present in significant nappy rashes and can occur on top of other rashes. It can be treated effectively with cream.

Chemical irritation

wee (urine) and poo (faeces) contain irritating substances which may lead to a rash if they are in contact with the skin for too long
too much soap can irritate the skin and dry it out
detergents and soaking solutions can irritate if they remain in the cloth nappy - wash and rinse nappies well

How can nappy rash be prevented?

change nappies as soon as possible after they become wet or soiled and preferably once during the night
clean your baby with good quality baby wipes or warm water and a cloth
let your baby have some 'nappy free' time daily, though not in the sun
avoid using plastic pants
wash and rinse all cloth nappies thoroughly
after each nappy change, apply a thin layer of protective cream to your baby's skin; for example, zinc and castor oil
try good quality disposable nappies

What to do if a rash develops

See your family doctor if a rash develops and lasts for more than a few days. It may mean that there is an underlying skin infection present such as thrush or a bacterial infection. Thrush is a fungal infection, which thrives in warm moist areas. It is almost always present in significant nappy rashes and can occur on top of other rashes.

Your doctor will usually prescribe a cream to treat the infection.

What about difficult to treat nappy rash?

When a nappy rash is difficult to treat, it may indicate that there is an underlying skin condition such as seborrhoeic dermatitis or psoriasis. This needs to be diagnosed and treated by a doctor.
