Here's how to nip it in the bud....do as much research on the bullies' parents as you can (i.e. arrest records, bankruptcy records, etc.), put all your findings in an envelope and send it to school with your kid. Have your kid to pull it out and show everyone why the bullies have such a horrible life and explain that's why they act like they do. This embarrasses the bullies so much that they never bully again! Trust me this works!
