I would like some help too. I have a four year old brother who I swear up and down has ADHD. I want to be a child psychologist when I'm done with school, so this sort of stuff really interests me. He is far beyond out of control. He is also a middle child, so maybe that's part of it. He just doesn't seem to think. He never listens to a thing anyone tells him too. He over reacts to little things. ie; he can't watch a movie, he will flip out and scream and throw a conniption fit like I killed his mom or something. He is rude and talks back and something isn't right. Another thing that scares me is how he responds to certain situations. This morning he dumped the entire can of fish food into the tank and killed all of the fish. He doesn't care. He's in trouble, and dad was trying to get it through to his head that he killed the fish, but he just shrugs. I also think he purposely hurts the animals and his two year old brother. He acts like it's on accident, but we tell him over and over that if the dog doesn't like it, he'll yelp. Or when he pushes his little brother, he'll cry. He is spastic and impulsive. I don't know if it's because he is a middle child, 4 year old boy or if there is something seriously wrong with him. I'm from a different family and I've dealt with lots of 4 year olds and none of them have acted like this. Can anyone help me?
