A. Hello mom its difficult to guess the exact reason that the child is not eating , it could be because of one of the reasons. Such as check his stools and urine output, also observe for bloating , if the quantity of the food intake is less than their usual intake And he is active for his age no worries , offer him fruits and fluids. To keep him well hydrated.
