Personally, I feel younger kids should be doing kid things like cycling, swimming, skateboarding, raising pets, and generally being close to nature
To me, it feels unnatural for younger kids to be wrapped up in interpersonal dynamics and cultural memes
I'm against banning anything, because it does never work. But kids should go out, be bored in some house entrance, sip milkshakes with friends and overall get that damn sun and air! Or do ship models, whatever, just stop staring into socmedia. It's the fault of the algorithm, it sells souls. There's a good book called in english something like "Hold onto your children" from Gordon Neufeld, highly recommend.
