Diet diary: Since your child likes fruit keep a diet diary to see if you can pinpoint which fruit is causing the problem and eliminate it from his diet for now.

May be intolerant: Some kids have a deficiency of the enzyme needed to digest fruit sugar.If they eat it, it can pass through without being absorbed and lead to acidic stools that are loose and scalding in nature.These leave a diaper rash that looks like a 1st degree burn. The approach to this issue is to avoid any fruit in quantity. When she is older she may tolerate the fruit better, but while in diapers, avoid.
