Description of technique:
When my son came home with complaints of a playground bully, we "brainstormed" about what could be done. We decided on an action (to tell an adult playground monitor he knew personally). I emphasized that he should communicate with the adult in a factual, not whining (tattletale) manner. He handled it himself, and the problem was solved. But, I made sure he knew that I would intervene if needed. I followed up with him to make sure the problem was solved. If it wasn't, I was prepared to go with him to the next level (teacher, principal, whatever) but still let him talk. It is important that the child take the action; with you there to back them up. It gives them the sense of control over the situation, with Mom or Dad's support/presence for reassurance. I would never suggest a child to just "take it" or "walk away". They need to be able to take action and not feel like a victim.
