Im sure there is some happy medium solution here, like putting your phone in a basket or cubby or something like that, at the very least. But I think this is something that has to be seriously addressed and considered. Phones are obviously bad for all of us, more so for children whose minds are far more elastic and far more prone to social alienation. The endless stream of notifications is almost at a gambling / casino level. I think you have to address the root cause of that as well
