I'm guessing this policy will be reversed pretty fast. No sane parents would leave their kids in an environment like this.
If I had my kid in there, I would pull my kid out so fast it would make your head swim.
Makes you think that the folks who raised kids on the farm or the ranch had the right idea:
Fresh air
Exercise
Meaningful work
Study
Good sleep ('cuz yer doggone tired)
Not much opportunity to get into trouble.
