In brief: Intolerance

Some kids who tolerate milk or bovine based formula early will become intolerant later in life.
Some speculate a gradual loss with age of the enzyme needed to digest the sugar in the milk (lactose). This leads to cramps & diarrhea.Those kids may tolerate small amounts without symptoms or other products like yogurt or cheese that are low in lactose.Lactaid milk is usually tolerated by this group.
