There may be weeping skin and sometimes a strong odour. If allowed to persist the reddened skin may become thickened and scaly. Some babies seem to get sore bottoms very easily, others very rarely, but they all grow out of it when they stop wearing nappies. There are several different kinds of diaper rashes, and some babies have a mild rash all the time that is of little concern. Almost all diaper rashes respond to the same treatment, which is keeping the baby's bottom clean and dry.
Atopic dermatitis occurs in people who seem to have very sensitive skin.
Almost every child will develop a diaper rash once in a while. Diaper rashes can vary from a mild redness, the most common kind, to painful open sores in the area of the abdomen, buttocks, genitals, and within the fold of the thighs. Diaper rash is due to urine or stool chemicals trapped inside a plastic covering rubbing against your baby's bottom and irritating the skin. If your baby frequently has diaper rash, take steps to alleviate the problem. It can result in discomfort for your baby and worry for you.
