My charge often plays with a 7yo boy who seems to think that hurting people (ranging from squeezing them to sitting on them to punching them) is really funny. Whenever I catch him I do call him on it, explain that it's not nice, that he is hurting whoever it is and he just laughs at me. He does this to his AP as well but she's a very sweet person and doesn't really stand up to him.
I'm not sure whether it's just that he finds it genuinely funny, whether he's embarassed at being caught or whether it's something else.
Obviously I'm not his parent, his AP has no idea how to deal with it, anyone got any ideas? Please help as it's getting beyond annoying and towards very stressful.
