In preschool, children encounter their first experiences in forming and joining social groups outside their family. It is natural for them to experiment with social interactions while learning about their world. In this guide, teasing and bullying are addressed as a continuum of intentionally hurtful behavior, from making fun of someone to repetitive physical abuse. Creating a caring environment at the beginning of the school year reduces the need for children to assert themselves through negative behavior such as teasing and bullying. The Anti-Bullying and Teasing Book helps teachers address this behavior before it develops.
