Back in the pre-medication days, people did just fine. Nobody went to the doctor and got prescribed medication because they were hyper or had this or that condition. They're just kids. They're supposed to be hyper and play and have an imagination. That's all you know how to do when you're a kid.
In younger kids, there is a tolerable level, and then there is a level where it just gets disruptive. At that point it should be taken care of it it can be. We have the means to take care of it now, why shouldn't we?
The fact that people did fine without it before medication was available is disputable and irrelevant. People also did fine with a cold, usually, before medication to treat cold symptoms was available. Should we also stop taking the 'tussin? I think not.
