I've already talked about how I was a victim of bullying as well as some tips that parents could use if their kids were faced with bullying. But this subject has gotten enough attention that there is a new website from the federal government with ways to help stop bullying.
At StopBullying.gov, among the articles are those that cover cyberbullying, bullying of LGBT kids, knowing the warning signs of bullying, and what kids can do about it. There are also several videos, including ones geared towards younger kids who might not understand what bullying is.
If you are faced with bullying in your child's life whatever the cause, StopBullying.gov has resources to help at least start a dialogue with your kids.
