My son is in y4 and is 8 years old. I had a phone call from his teacher today to say that he had been involved in an argument with about boy during a game of football and he hit him between the legs. He has never ever done something like this before and even the teacher was shocked. He has admitted to it and apologised to the other boy and both are apparently the best of friends today. He missed his breaktime as a punishment but I feel he needs to have another one at home. He know he is never allowed to be physical..especially hitting someone between the legs . He's a normal 8 year old..he does have the occasional attitude and strop but this is so out of the blue. Any advice in how to deal with this would be very appreciated
