I have a child in my class who has become so difficult, and I am running out of ideas. He has a few behavior issues, but the biggest one is that he hits all the time - mainly targeting one other child. I feel so bad for the other boy. He is a sweet kid who doesn't hurt anyone, and is constantly afraid the other boy will hit him. I know the child is hitting out of frustration. He wants the other boy to play with him, and hits him when he doesn't do what he wants him to. Here's what I do/ have done: I keep modeling for him how to ask to play, or express his frustrations. I remind the whole class every morning that our #1 one rule is to "Be kind," and what that means. I've done activities on sharing, not hitting, and even modeled conflict resolution with puppets. I constantly use positive reinforcement when he uses his words, shares, or handles a conflict without hitting. I tried a reward chart for a while, but it didn't seem to work, and the kids were too focused on the prize so I stopped it. I tried TO for a while, but he will sit in TO then get up and immediately hit again. It doesn't seem to work for him. And I don't want to put him in TO all day either. I do still put him in TO when he uses a weapon - which he often does (i.e. metal tongs, cars, dolls etc) Every day, I'm telling him that if he hits he won't be allowed to play with the other child.. and I follow through. Then after a while, I ask him if he's ready to play without hitting, and he says yes, but it doesn't stick. I keep telling him that the other boy isn't going to want to play with someone who hurts him. Separating the two is really hard since I run a home school with only 6 kids and one me. There is only one sandbox, one swing set, and one snack table so I have to be on top of him all day. This is very hard when I have 5 other children to manage. He hit sometimes before, but it got considerably worse when the new boy started. His mother said that he was doing it to his father for a while, but it has stopped. She takes him to playdates with other kids without issues. I wonder if that's because she watches him so closely all the time. He always seems to do it the minute my head is turned. I don't know what else I can do, or if maybe I'm unknowingly doing something wrong. Any advice you can give would be so helpful. Thanks!
