Empower the kid. Enroll them for self defense classes. It will build their confidence and perhaps shift perspective from being a victim. If all else fails, talk to the school and make the bully their parents responsibility.
Today's world has a hard time dealing with bullies because there aren't any good solutions that won't get the bullied person in trouble as well.
Hit back and you both go to the principal's office.
Tell the teacher and you might get bullied more and called all sorts of names and teased by others for being a tattle tale.
Do nothing and everyone suffers more at the hands of the bully.
The establishment wants you to tell them about it. The kid can help themselves out by not involving their parents, telling the teacher privately in the hopes they increase monitoring without blaming the bullied for tattling.
The parent can help out by teaching the bullied kid soft martial arts where they put the aggressor in a hold that prevents the bully from hitting but doesn't leave a bruise on the bully.
Yes this is hard because there’s a lot of bad consequences for getting involved physically. But I can’t emphasize how it important it is to establish precedence. People need to know that picking on you will cost them in the back of their mind.
My parents always taught me to go the most peaceful way but I kind of regret it. The kid needs to earn space and respect. If he/she is being invaded physically , he/she needs to respond the same way. Teachers won't be around forever
What kind of bullying and why? Just one or more? Voting tell the teacher first and you probably need to as well, if they don't do anything see if you can contact the parents and then if no one does anything tell them you and your kid will do anything necessary to defend themselves.
Btw if it is physical punching hard and a bunch of "boys being boys" your kids life could be at risk so don't just ignore it.
