First of all, if I saw my child doing the bullying, we would be done at the park immediately and there would be severe consequences at home! Bullying is not to be tolerated, no matter how young the offender. Children need to be taught empathy!!! If it were my child being bullied, I would not yell at the other child. I would never yell at someone else's child unless it were a life or death (or extremely serious) circumstance. I think I would try to talk to the other child and see if I can get that child to feel empathy. If not, then I would tell my child to find someone else to play with and just tell the child to leave mine alone. If that didn't work, I would take my child and leave. Again, the reason we have so much juvenile crime these days is because kids watch horrible violence on television and in those stupid video games. They grow immune to human suffering and pain - they don't feel empathy! We need to teach our children to put themselves in the other person's place and think about how they'd like to be treated and then act accordingly. If we don't re-start teaching empathy, we will end up with a society of sociopaths!
