Thanks for your query.
I understand your concern.
in children is related to diet intake,
.fissures and hurshprung's disease needs to be ruled out.
Laxatives should not be used for longer duration.
I suggest you to give him plenty of fluids,glucose
water,green leafy vegetables.fruits,salad.
Give one spoon of honey with warm water at bedtime.
Decrease milk products,avoid all kind of junk food (candy,chocolates.chips soft drinks)
Your child will be fine soon.
