my grandson is two year old is hyper active. keeps moving/running all the waking hours, has tendency to throw things around and hit others. the way he smiles after such episodes, he smiles indicating some pleasure derived. He does more of that if asked to stop or admonished. All the same, he is pleasant in his demeanor. he has some preferences like a booklet containing photoes of animals, birds, vehicle etc. is this a passing phase or you recommend some consultation
