If you don't set the rules very early, you're at their mercy.it's easy to blame parents. i kept my son off of social media till he was 15, but you can't raise kids in a vacuum. they spend most of the day at school with their peers and not under the parent's guidance. when at home they are doing homework or some other extra curricular crap. there is very little home life and the influence on kids is mostly their peers. when you have an argument with your kids it's you vs your child plus his peers plus social media. you will lose most of the time.
