Nappy rash: What causes it, how to prevent it and how to treat it


Brought to you by Caldesene

Worried about nappy rash? Here’s everything you need to know.

Most babies are likely to experience nappy rash at some point, and as parents, it’s so important to understand how we can best care for our child’s sensitive skin. With this in mind, we’ve teamed up with Caldesene to bring you the ultimate guide to recognising, preventing and treating nappy rash.

So what exactly is nappy rash?

Nappy rash is a form of dermatitis, a skin inflammation that appears as a bright red rash on your baby’s bottom.

What causes nappy rash?

Nappy rash is the result of bacteria reacting with your baby’s urine causing a chemical reaction that can irritate and damage their skin. This can happen due to a number of reasons such as:

  • Leaving a wet or dirty nappy on for too long
  • A bacterial or yeast infection
  • Irritation from a new product
  • Starting solid foods
  • Teething
  • Chaffing or rubbing from tight-fitting nappies or clothing

What does nappy rash look like?

Nappy rash will make your child’s skin appear red and sore. It may be irritated, chapped or swollen in some places. Nappy rash can occur in a small area, or your baby may experience nappy rash over their inner thighs, particularly in skin folds and creases.

Can I prevent nappy rash?

There are a number of steps you can take to prevent nappy rash. Start by changing your baby’s nappy as soon as it’s wet or soiled and then wash the area carefully with damp cotton wool. Make sure that their skin is completely dry by pat or air-drying. Do not rub their skin. Before putting on a new nappy, sprinkle a layer of Caldesene on their skin. As Caldesene is medicated, it attacks harmful bacteria and prevents nappy rash. It’s also specially formulated to create a barrier against wetness on your baby’s skin. Then, when you put their nappy on, make sure it’s not too tight.

It’s also a good idea to allow your baby’s bottom to breathe. Fresh air is good for their skin. Pop a clean towel under their bottom and allow them to play and kick about without a nappy on.

My baby has nappy rash – what can I do to treat it?

Gently cleanse the affected area with a soap-free wash and then pat or air-dry their bum. Sprinkle a layer of Caldesene at every change, or as directed by your GP or pharmacist. Again, let your child’s bum breathe as much as possible by allowing them to play and kick without their nappy on so that they get fresh air on their bottom.
