Brace yourself. It's a pain in the ass!
We have limited screen time for our kids on weekdays. Probably not as limited as it should be, but enough to cause constant grief. Holy shit the arguments and raging it's caused! We've been called nazis, prison guards, micromanagers, helicopter parents, you name it. So for our limited screen policy and implementation of it. I've had to get a bit of drywall repaired because one of them got so worked up he kicked the wall and broke it.
I hope some day they appreciate we were only doing it for their own benefit. But who the fuck knows.
