A boy(3) Is responding with aggression (kicking the floor, says he's gonna hurt me, using angry voice, etc) when being asked to do something he prefers not to do. Today he promised to scratch his uncle's eyes out and shoot him. Sometimes when he calls for someone and doesn't get instant response, he starts screaming at the said person. If he'd be an adult, I'd definitely say he needs anger management. This behavior is not something he sees at home, his older brother (5) never behaves like this. Is this something kids usually grows out from? (I ofcourse do my best to make him realize that this is not tolerable behavior). Or is it something that requires the involvement of a specialist (cannot think of a better term) immediately.
