01 · Know
What is Nappy Rash?
Nappy rash is a common skin irritation in the nappy area, usually caused by prolonged contact with wet or soiled nappies, friction, or sometimes a fungal infection. It typically causes red, sore-looking skin, and babies may seem uncomfortable, especially during nappy changes.
It's extremely common and usually improves within a few days with simple changes to nappy care, though persistent or worsening rash may need a specific treatment.

Clinical context
Air time helps healing significantly
Giving your baby some nappy-free time each day, allowing air to reach the skin, is one of the simplest and most effective ways to help nappy rash heal.

Practical steps
Change Nappies Frequently, Even Overnight If Needed
Reducing the time skin spends in contact with a wet or soiled nappy is the single most effective way to prevent and treat nappy rash.
- 1Change nappies frequently.Check and change as soon as possible after your baby wets or soils their nappy.
- 2Clean gently and pat dry.Use plain water or fragrance-free wipes, and pat rather than rub the skin dry.
- 3Give nappy-free time.Letting the skin air out for short periods each day supports healing.
- 4Apply a barrier cream.A simple barrier cream at each change can protect the skin from further irritation.
- 5Avoid tight-fitting nappies.A slightly looser fit reduces friction against already irritated skin.
