I do wish you luck. Remember that he may need some ideas for what he SHOULD do when he is upset. Give him appropriate things to do so that he learns what he can do if he feels mad at someone. That will help him grow up to handle his anger and frustration in ways that are okay and give him the best chance of resolving the problem. Good luck for sure!!
He does watch alot of TV and I just recently found out he was play a game with his older cousins that was way too mature for him. It had alot of killing,blood,shooting, and bombing, some cuss words. I was very shocked to find this out, but I do blame myself for not monitoring what he is watching and playing.
I have taken away all his guns and army toys. I have talked to him about how scary it sounds to someone to hear those words. I told him they can call the police and they might have to take him away. He seemed to get it. But I am watching every thing he does. Wish me luck and lots of prayers.
It sounds like your boy is watching a lot of tv, playing video games, or hanging out with some older kids. He's learned to say something shocking when he is upset. I think I would try to talk to him about it. What else can a 6 year old do with their anger or frustration? Give him some alternatives and help him learn to express what is really wrong vs the shocking statement. Role play some scenarios with him in which he tries these alternatives. Also let him know that the shocking statements could get him in trouble. These days, mentioning a bomb in the wrong place gets classified as a terrorist threat . . . kids don't understand the power of their words. Help him understand that . . . and then give him something else appropriate to do with the emotion he has. Good luck.
