My son has always had an aggressive side to him. To give a little background before going into the present issues: his dad was always told he was ADHD. Later as an adult he was told he had bi-polar. As an infant I had to have help with my son because before 1 he was physically aggressive. Up until recently I always thought it was learned behavior from seeing his dad attempt to abuse me. I am divorced and he has been completely out of our lives for 3 years. After our divorce my sons aggression was always towards others trying to hurt someone else, he was being protective. I noticed at 4 he would hit my mom out of anger. Being a single parent in the military we went lengths of him being with her. Now that I been out I have noticed him getting worse over the past 2 years. His behavior is back and forth at school and most of the times he's in trouble it for being the clown but he has hurt others. If he's getting in trouble or were trying to have a serious conversation with him he will laugh in your face. He never takes anything seriously. He will purposely try to make the dog hurt the cat. The dog and cat play but it has to be watched because our large puppy gets a Lil rough. I caught my son pulling the cat off something by his tail to give him to the dog. He thought it was funny even though he knew it would hurt the cat. He has kicked the dog in the face over and over after he started wrestling with her then couldn't get her off. He has hurt his step brother on purpose. He is very very smart, manipulative, lies out his teeth and shows no remorse when he hurts others. He loves to play with fire. He is only concerned with himself. He is a very good actor when he wants something but if you do give it to him he goes right back to being bad. I am losing complete control. My old fashioned whoopens only seem to excite him. I have tried positive reinforcement along with everything else I can think of. I really believe he is a sociopath and he is becoming dangerous. I'm goin to take him to see someone but I want some opinions. I do believe he is just like his dad but I don't think he's bipolar. My mom says no medications but I don't think I'm going to have a choice...he is on the verge of seriously hurting someone. Has anyone experienced something similar and what was the diagnoses?
