Our government’s line is specifically that children are statistically less likely to transmit it. And when they do it requires longer and closer exposure - ie, is more likely to happen at home.
As I said, I am sceptical but that is definitely the line they are trying to sell, in a separate message to also selling ‘kids don’t get as sick anyway’.
I think one of the misconceptions is that kids don't get sick. I live in NYC, and here there's been a lot of cases of a Multisystem Inflammatory Syndrome in Children caused by COVID-19. This affects anyone under age 21 (even healthy kids with no underlying conditions!) and it can be very deadly!
