Re: “nudge them towards different content”
When I was six years old my mum talked to the library manager and got me a set of "Adult" tickets which made me so happy, I could head home with a couple of Biggles books (I have read so many of W. E. Johns books), and some books about research into early telepathy testing and human evolution. And then I started reading about how to start drawing ... lots of books with illustrations of the naked human posture that showed how to draw accurately.
So I believe that limiting children to little kiddy events and preventing them from seeing the adult environment has the potential to result in problems - as adults we think we're smart but actually (just look at current politics) we can be stupid too. It's best to teach kids that stupidity is normal but needs to be avoided.
