If you never give it back, then there can't be any more rage from turning it off.

I've skimmed the article but did not found the answer to the title. My childhood was marked by random internet shutdown from my parents during online game, computer shutdown...I can tell I experienced the frustration it can generate to a child. And it actually had me more hooked, as the scarcity and the "shutdown risk" and the accumulated frustration led me to try to play whenever it was possible.

Now I have a kid, and a tablet, and the best way to let them go is to watch things together, propose other things rather than a "stop it now it's enough", avoid doom scrolling pattern, short content...One must avoid creating uncontrollable frustration, that's what make kids crazy.

And even better if tablet can be avoided most of the time, they tend to forget it.
