I have an aide who is also a parent of one of my students. We need some help with coming up with a behavior plan for her son. He's been doing a lot of pushing and yelling at other kids, and a lot of whining on top of it. She does time outs at home and talks to him about how all this makes other kids feel. We do the same at school. It doesn't seem to be working- yesterday he spit in another kids face at recess, and mom was in tears. Any suggestions, or even on books or websites that will be helpful? The kid's sweet but he's big for a Kinder and very active.
