Description of technique:
My Kindergartener was being bullied by a classmate for months.
Our best solution was talking with the parent and explaining what was going on and then planning a play date with all of us to let the bully know that we're all really the same
no matter what color we are or size. This helped and, no they are not best friends, but the bullying has stopped completely. Also, getting a couple of buddies to stay with you through out the day cuts down on bullying because he is outnumbered.

Age group this technique is effective for:
Elementary School
