Many children rebel through clothes, music, and extreme behavior. How would you react to your child

To my relief, my three children have been obedient to us on the whole so far. Sometimes they were late for school or they cut the cram school’s classes occasionally. I don’t think my children come to adolescence when children often show unexpected behaviors. I think my children could rebel against us in their adolescence by showing what I don\'t expect them to do as other adolescents do. In case of that, I will have a heart-to-heart talk and try to share the experience of my adolescence in the hope that it might help them. And I also try to lead and help them to spend their wandering time with good hobbies, sports, good friends as pre-emptive actions.
