Nappy rash is very common.
The best way to treat ordinary nappy rash is by changing the nappy regularly and also allowing the baby's bottom to get some fresh air. It is not usually a disease, but just an irritation of the skin. A wet or dirty nappy that has been left touching the skin for too long is the most common cause of nappy rash. This is especially true of children with diarrhoea . Human waste products can turn into ammonia if the nappy isn't changed for a long time.
