I am a nanny for 2 boys, one is 5 and the other 9. The older boy (S) is prone to having these violent, angry outbursts whenever he feels like his brother (N) has done something wrong. For example, this morning they were riding bikes before school and N (accidently) ran into S with his bike. S immediately started screaming his head off, so I told N, "What do you say when you accidently hurt someone?" and N apologized. S kept screaming about it and then intentionally ran into him with his bike and slapped him in the face. I pulled S aside and took away the bike and told him it's not okay to hit someone no matter how angry he is. And he just kept yelling about how N wouldn't leave him alone, so I told him that if he feels like he needs space then he should tell me and I will make sure N doesn't follow him but that he can not hit anyone. Things like this happen at least twice a day, on a good day.
Their parents seem to have this "S, don't hit him and N you shouldn't be following him, anyway" sort of attitude and don't do much about it. But S is so much bigger than N that I really worry he might hurt him... and in general, I don't want this kid to grow up thinking he can hit people whenever he's angry.
Anyone have any ideas about what I can do? I think he just needs to work on having an appropriate outlet for his anger, but I can't really come up with anything. It seems like walking away wouldn't help because he gets so overwhelmed with anger in the moment that he can't stop himself and it only takes him about 5 minutes to cool down and move on. Time outs are just not feasible because this morning he had to get on the bus for school so I couldn't make him sit somewhere.
The kids parents work all the time, so I have them from 7am - 7:30 or 8pm every day (except the hours they're in school, when school is on holiday I have them all day).
