Bullying isn't a "normal part of growing up" if a child is being bullied physically that is a failure of the school to protect them and a failure to create a safe learning environment.
Psychological bullying is equally as serious but can be harder to identify. But if a child/teen comes home from school upset repeatedly. If they say they don't want to go to school. If they alter their behavior to avoid persecution this is also a failure.
This feels obvious and basic but I'm saying it anyway.
