As Parent Of Older Kids and grandkids, Trust is the biggest thing you need to work on. You need your Kids to trust one of you good enough to talk to you when things are not going well. If they can talk to you half the battle won. As a grandparent, I have a bigger advantage, because I don't see them every day, the changes in there personalities and behaviours are easier to spot.
The next part is how to stop the bullying.
Physical bullying can be an easy fix, I taught my Kids Martial Arts, and along with other team events they had a network of friends around them. and there was a strong emphasis on the need to help others, against Bullying. Again you have to listen and understand your kids.
Social Media is the hard one. from experience, you have to make an environment where they will talk to you.
But more importantly, you also must learn how to Look, Listen and Feel the signs. If you think something amiss never be afraid to investigate.
PS listening and understanding does not always mean agreeing with them, they have to learn right from wrong.
But remember Bullying is not just a kids domain.
Completely agree. Learning how to read your kids emotions and body language can be quite hard, especially as they mature. Building trust is absolutely key.
I brought my kids for a while to my martial arts club but couldn't get them past 3rd kyu! Still, i hope that should be enough to stop a physical bully at school.
Something i've found that works well with my kids is if i get home from work, grab the dog take it for a walk and bring one of my kids along for the walk. I don't say much at all, they will usually relax and start a conversation with me, quite often they will open up about how school is going or problems with a friend or whatever is on their mind, not realising that is exactly the reason we have gone on the walk.
