Hey Jr! Hyper active kids can really wear people out. :) I think you should try and let the hyper active tot use his energy on fun physical activities. Try different sports or even enroll them in some dance classes. They'll be spending their energy on something productive and they'll for sure enjoy themselves. :)
I agree, if the kid is not diagnosed with ADHD it is usually a surge of energy. I read about an article that encourages parents to let their child play until they become exhausted because if not it would not be good for the child's health. It's as if you're depriving him of physical development.
