I've seen lots of material online and from my daughter's school about how to respond to cyberbullying. But if I can prevent it from happening in the first place, that's even better. All parents should know the top 10 ways we can prevent cyberbullying.
Promote self-esteem and confidence. Encourage them to find activities they enjoy and develop skills to be proud of. Confident kids are less likely to be picked on, and they're also better able to shrug off bullying if it does happen
Let them know it's okay to confide in you. Kids need to know that they can tell you anything – good or bad – and you won't over react.
