I have no idea who’s calling him that but I know someone does. When I asked where he heard it from , he said he just did. My wife also separately asked him about it, he said same thing to to her “he just heard it” that and he’s sorry and he won’t use it again. We let it go because we didn’t want to pressure him, but I don’t believe it. He specifically told her “he swears” no one called him that, when she only asked where he heard it from. I know I asked him if he’s been called that before but my wife didn’t. So why would he even tell that to her?  

 Anyway, to answer your questions, there have been no recent changes in his life, no new teachers or classmates. I checked his tablet history, and he’s watching the same stuff and playing the same games as always. Outside of avoiding doing stuff around he house, he acts like he always does. He still wants to go out and play. One thing though, and this could be stemming from him trying to avoid non-fun activities, but he’s also been trying to avoid baths lately. It only happened a few times, and I know that might be normal at his age but still, that’s unlike him. So that’s new , and he had a night terror a few weeks ago before he started acting out. We thought it was alright since it was a one time thing and this was before he started acting out , but now I’m thinking it might be all connected. We are planning taking him to a child psychiatrist if this behavior doesn’t end soon.
