Some children do show tendency to be over active as their brain works too fast. You need to challenge the child physically by enrolling him in different activities so it tires him. Teach him to complete his work what he starts without getting angry. You have to start the role of an authoritative parent when it comes to good manners, staying quite while someone is talking, at a young age. The child should be made to feel that he cannot get away with somethings in life and you have to be very consistent particularly when the child is more active than normal.
