Signs your child is being bullied could be: unexplained injuries, faking illness as to not go to school, self-destructive behaviors, loss of friends and/or avoiding social situations, low self-esteem, etc.
Signs to show if your child is a cyberbully are: changes in behavior, they may act more aggressive or defiant, grades will start to lower, or your child may act more secretive. If your child is acting differently you could talk to them or a teacher about their behavioral changes.
As a parent, limiting the time your child is online or access all together could help prevent cyberbullying. Knowing what your child is posting and monitoring them will help keep your child and other children safe online.
