I fully agree. My children are learning by doing, I encourage them to make mistakes.
Banning them from stuff (or screen) is not part of that strategy. I also not monitoring them (just I don't like to be monitored, I treat them as I would like to be treated as child).
What is shocking to me, is that I have less and less agency over time as a parent using YouTube (Kids). The agency is moving towards to the players who are in there for the profits. And those profits are being made at the expense of our well-being. That's disgusting. That's a big price we're paying. Many people out there are not aware of that (that's my opinion / expierence).
