Bullying can lead to long term effects on a kid. Understanding what bullying is and how to cope with it can help kids develop confidence and also be a better person. Usually bullying is a learned response and kids who see bullying at home or school tend to bully others in return.
A comprehensive coaching of the kids can help them cope with bullying easily. This will also help them in not becoming a bully themselves. This avoids the long-term psychological effects resulting from bullying.
