My 7 year old son has started using words like 'kill', 'murder' and 'stab' when he's playing with me or other kids. He's not angry or violent about it. For example we might be playing/pretending to be ninjas and he'll say "I'm going to murder you".
His school teacher emailed his mother and I and said that his use of these words had upset some of the other students. I can't help but think it was more upsetting to the teachers than the students since, again, he uses these words in the context of play and has no history of violence. Indeed, he's an extremely sensitive boy and will get weepy when I do nothing more than raise my voice.
His mother is very concerned about this and wants to get him into counseling. I'm less concerned and am more willing to chalk it up to behavior befitting a 7 yr old boy.
Should I be more concerned than I am? Is his mother overreacting?
Thanks in advance.
