I think you are on the right path as far as limiting what a 4 year old child watches on TV. Especially a child who already has behavior struggles. I also agree with what others have already stated in that the big time wrestling did not cause his behavior problems - but will do nothing to help.

My son had severe behavior problems when he was little (3 years old) and what we eventually discovered was that he had learning disabilities. He had difficulting regulating his emotions, understanding facial expressions, sensory integration disorder, and is dyslexic. He also had a great memory in that all he had to do was watch something one time and he had it memorized. And there are certain phrases within most movies that you just don't want your 4 year old repeating !

We watched Disney's Hunchback movie and there is a part in that movie where some poor guy was in the stocks and during the commotion of the gypsy getting away and all the guy was accidentally set free. The guy exclaims "I'm free !!". Then the guy trips and falls into a little cage and says "dang it". Well - didn't we just get to hear that little phrase ALL THE TIME.

We also noticed that our son would take on the persona of whoever the "strong" personality was in whatever he watched. If it was the prince in sleeping beauty then he was swash buckling the furnature, drapes, dog etc with anything that even resembled a sword. Which was certainly not a big deal at home but in daycare - that was a problem. Whenever my son would feel overwhelmed or believe that an injustice had just occurred .. he would swash buckle someone. And it didn't seem to make a difference to him how often he was punished.

Sorry this is so long, but my point is .. with a child like mine who was struggling with his behavior anyway .. and who was drawn to the "tough" guy persona as a role model .. the last thing I wanted was him watching big time wrestling or anything with Clint Eastwood !!

I totally think you are on the right path to limit aggressive TV/Movies and games from your step-son's viewing. Meanwhile, you and the child's father very much need to investigate how you can help this 4 year old manage his behavior.

p.s. my son is 14 now and he is doing great ! he watches movies that are PG-13 but the violent R rated movies are still off limits. ditto with the violent video games.
