My 2.5yo boy has been hitting, scratching abd throwing things for no reason. He isn’t emotional every time. Sometimes he is happily playing and next moment HUGE SLAP 💥. Despite everything we have tried he seems getting worse. He caused multiple injuries in his nursery every day. I an afraid he’s gonna kicked out. We have tried telling him to stop firmly, teach him gentle hands, praise him when he is gentle, timeout when he’s doing it, have him face the wall, take away the toys he threw, teach him no hitting with plushies…I can distract him but it doesn’t seem to solve the root cause. He can be demonstrating “gentle” to me and then scratch the hell out of me next second. I snapped just now and I am feeling terrible now, but I don’t know what else I can do.
