    Causes, incidence, and risk factors

    Diaper rashes are common in babies between 4 and 15 months old. They may be noticed more when babies begin to eat solid foods.

    Diaper rashes caused by infection with a yeast or fungus called Candida are very common in children. Candida is found everywhere in the environment. It grows best in warm, moist places, such as under a diaper. A yeast-related diaper rash is more likely to occur in babies who:

    • Are not kept clean and dry
    • Are taking antibiotics, or whose mothers are taking antibiotics while breast feeding
    • Have more frequent stools

    Other causes of diaper rashes include:

    • Acids in the stool (seen more often when the child has diarrhea)
    • Ammonia (produced when bacteria break down urine)
    • Diapers that are too tight or rub the skin
    • Reactions to soaps and other products used to clean cloth diapers
    • Too much moisture
