I don't know what to do anymore with my son's behaviour. He's not listening at all he doesn't takes us seriously not even a little bit he only listens if i shout. He's constantly hitting his dad and his little brother without even a reason just he's in the way. Sitting on top of him laughing while he screams under him. I can not reason with him because he's not listening or he covers his ears so he wouldn't hear me talking. Not playing with toys just making a mess all the time or destroying stuff. He's weirdly friendly with strangers and stranger kids his really gentle. I dont know how to deal with him or how to make him happy anymore. Please help because im gonna go crazy.
