How do you deal with your child if you found out that he/she is a bully?

This article I found on dealing with a child who is a "sibling" bully, will definitely help. If your child is bullying anyone, in your family or otherwise, the tips in this article will definitely help. For example, if I found out my child was a bully, I'd teach them "that their actions have consequences. Give them a “time out” whenever they lash out but make sure they understand that it’s more of a time to reflect than a form of punishment."
