The kids will figure it out like you did. Maybe the terrain has changed, but there was noone to tell you whats what back in the day anyway, so why worry? Or rather, emotional maturity can go both ways here: jumping to a paternalistic mindset will rob you the wisdom the kids themselves can give. I think its natural and probably right to feel concern, but don't overcorrect it into presumption or into a false idea that you can just give to kids what you had to learn/discover yourself.
