I am watching my sister's son (and her two other children) today. Her son, who is 6 1/2, bites, kicks, hits, lies, and is really a bully. He tries to trick people so he can gets what he wants, and is always saying mean hurtful things to people (me, his siblings, my kids). He kicked me in the chest (hard) a few weeks ago. He is always hitting. Today he bit Jasper (Jasper is 5 and never hits, hasn't in about a year). Do you think it is normal for him to hit and treat others, and me like this? I know that my sister has been told that he is having problems in school. He hit his swim teacher at swim club. I feel that it is not normal and so when he does it in my care, I give him LOOONG time-outs to prevent the behaviour in the future, which works to some extent. This morning he had a 1/2 hour time-out for biting. I am at the point where I don't want him around my kids or my house. When he kicked me a few weeks ago, he did it so hard that I flew back and almost to the floor. I am not sure what to say to my sister as she doesn't think it is a big deal, and isn't one to take critism well. Her son's school teacher brought up behaviour issues, and my sister told his teacher that he only acts up when her son isn't challenged enough and basically pinned the blame on the teacher!!!! I am lost as to what to do. HELP ME! I am actually becoming scared of him, that he will seriously hurt one of the other kids, or me.
