I don't recommend your daughter to drink it. Pocari Sweat is sport drink so that means it contains mineral (electrolyte). For small kids, drinking this kind of drink is not good, you know, It's the same why you don't recommend pregnant women to drink mineral water. You don't like to see electrolyte level in this kind of sensitive people swinging. I think it's more harm than good.

(I don't read any research or know the ingredients of Pocari. I just guess from the information I see on this topic with my knowledge as a pharmacist. It may not be accurated)
