Every time my son is in a situation where he doesn't win at something, whether it is playing tag or getting the last word with a sibling, he gets extremely angry. He is a laid back typical 7 year old boy until he loses. He begins to turn red and get angry and if someone laughs because he is acting so ridiculous he starts crying and stomping. I have tried telling him he can't play tag until he loses the first one and doesn't get angry in an attempt to try to desensitize him to losing. He really tries and then starts to get angry after a minute and goes back to his routine. I have had long talks about how it's not important if you lose a game, just have fun. I have acted like him to show him how he looks. He usually laughs when i do this and realizes he has a problem, but he can't stop from getting angry even if we go back to the game immediatly after the conversation. I really need something to help him overcome his persistent urge to win. What shoud i do when he acts like this? Have done time out, grounding and have even spanked him when he kicked his brother once ( he rarely ever physically lashes out at others). Nothing seems to help!!!I want to stop it now before he gets older and he gets worse. He is very intelligent and actually gifted in reading comprehension. He is caring and sensitive to other's needs and has lots of friends. He does not have emotional issues or behavioral problems other than this one tic.
