@LoftyRobin i think it’d be a good idea for you to look up some of the more data / science driven research around allowing children unfettered access to the internet. You seem to be going on your feelings and, unfortunately, you are not an expert.
Lack of frontal cortex development means children are physically unable to reason and manage themselves online like older teens/ adults can do. It’s not something they can ‘learn’ until the brain is developed. It’d be like asking a 1yr old to learn to do maths by continual exposure. It can’t happen until the brain is ready.
A poster above has linked a couple of books that are great starting points here.
My 11yr old is very ‘street’ wise about the internet and we have continual dialogue about the good things and the bad things. What she doesn’t have is unfettered access to social media like TikTok as it’s not age appropriate or safe.
Even on Pinterest, which she uses for moodboards, she’s been served content that is pro-anorexia. We have an open dialogue so she chatted with me about it, but she was really really unsettled. And this is the more mild end of the internet Wild West.
