My child sik suger he six year what can i do?

Can you clarify your: Question. Does he get sick as in has diarrhea from intolerance of cow's milk sugar ( lactose) or fruit juice sugar ( fructose) ? These can be solved by using lactose-free milk or lact-aid chewable tablets before ingesting milk or milk products & by avoiding juice altogether. If he eats too many sweets, it's best not to allow them in your house. Talk to his pediatrician about your concerns.
