School is back in session and unfortunately for a lot of children that means bullying is also back.

Dr. Wendy Craig is with an organization called PrevNet.

PrevNet is a national network of leading researchers and organizations, working together to stop bullying in Canada. It is the first of its kind in this country and a world leader in bullying prevention.

Through education, research, training and policy change, PREVNet aims to stop the violence caused by bullying - so every child can grow up happy, healthy and safe.

Today on Connections Dr. Craig helps us learn how to spot signs of bullying, prevent our own kids from becoming bullies, and what to do if we or our children witness bullying.
