The problem is that screens are just scarily addicting for kids. They have limited, supervised screen time to less than half an hour a day for the youngest (5) and around an hour a day for the eldest (8), yet despite that it's practically all they care about. The only thing they seem to think about is getting back mum's phone so that they can watch youtube or whatever it is they do, despite it being such a short part of their otherwise eventful days.

Hell, I've got a Steam Deck that I bring with me whenever I come around to visit, yet they don't care about it at all despite my steam library having around 900 games, they'd rather use my phone!
