Diaper rash (nappy rash) is so common in babies and is often a cause for concern for mothers. This page discusses the likely causes and the options for treatment and includes a photo of a diaper/nappy rash.
You can click on a link to a specific question below or just keep reading for an overview.
It is a rash in the diaper or nappy area due to irritation, usually by moisture. This can occur because you live in a warm, humid climate or because of irritation to the skin from the urine (and chemicals in urine like ammonia) in a wet diaper or nappy.
Babies can also get a diaper rash (nappy rash) due to thrush, which is an infection with the yeast Candida. With thrush, there are often discrete spots (we call them satellite lesions) scattered around the rash as well. To read more on thrush and to view a photo, click here.
Babies can also get seborrheic dermatitis in the diaper (nappy) area. This rash has a waxy, greasy slightly yellow appearance and does respond to topical steroids. Seborrheic dermatitis on the scalp is called Cradle Cap. Read more
The skin in the diaper (nappy) area is red and can have scales. The skin in the creases of the thighs is usually spared as the moisture doesn't reach inside the creases.
The baby in the photo has eczema as well, as you can see on the baby's trunk. Eczema makes the skin more likely to become irritated, so if the baby is in wet diapers (nappies) for too long, he can easily get a diaper rash.
To see the photo to the right, hold the mouse over it.
Sometimes, if the skin is very red and inflamed, a course of steroid cream (1% Hydrocortisone) will be necessary. This is more likely in infants between 9 and 12 months of age, and if the rash is thought to be seborrheic dermatitis - so has a waxy, yellow appearance.
See you doctor
