What is nappy rash?

Nappy rash, also known as diaper dermatitis, is a common rash that appears on a baby’s bottom – usually on the skin where their nappy sits2. It’s usually developed by infants and children under two years old, though adults can suffer from it too2.

It presents as a redness and/or soreness on and around your baby’s bottom or genitals3 and is often caused by friction and irritation from their nappy if they’ve been wearing it for too long2. While it can be distressing for both you and baby, it can often be treated at home4.

What causes nappy rash?

There are a few different nappy rash causes. It’s a good idea to be aware of these so you can start working towards prevention while keeping an eye out for some possible triggers. For example:

  • Bacteria. Your baby could develop nappy rash if you don’t clean them or change their nappy often enough4.

  • Urine and faeces. Similar to the above, the rash can develop if your baby’s skin has been in contact with urine or faeces for a long time4.

  • Fungi. Babies can develop thrush, which is a fungal infection that also causes nappy rash4.

  • Friction.For example, when a nappy rubs against your baby’s skin4. Sometimes, leaving your baby out of their nappy for a while can help2.

  • Allergic reactions. Your baby’s skin might be sensitive to some soaps, bubble baths, or detergents4.

  • Some chemicals. Similarly, some babies’ skin can be irritated by certain fragranced products – for example, baby wipes – or products containing alcohol4.

  • Medicines. Sometimes, certain medicines, like laxatives or antibiotics, can cause nappy rash4.

Preventing nappy rash

Most nappy rashes are mild and can often be treated and prevented with simple skincare steps. For example4:

  • Changing wet or dirty nappiesas soon as you can.

  • Making sure your baby’s skin is clean and dry. Gently pat or rub when doing so.

  • Cleaning their skin using warm water, and avoiding products that use strong ingredients, like alcohol.

  • Bathing your baby regularly to help them stay clean. Try not to do this more than twice a day, as this can dry their skin out.

  • Making sure you’re using the right nappies. Ensuring they fit properly means there’s less chance of them rubbing.

  • Similarly, using extra absorbent nappies to keep them as clean as possible.

  • When you can, leaving your baby without a nappy for periods of time, to let their skin breathe.
