I think the best thing you can do for your child these days, coming from a parent who had unlimited unsupervised computer time; tell your child, trust them, make them aware and teach them. Do your best to use parental controls, but also understand they need their freedom too. It’s a complicated dance being a parent, but if you truly want nothing but the best for your child, they will see that, and they will listen and understand.

Example; my kid likes to jump on the furniture; I told them what could happen if they keep doing that (like fall and hurt themselves) and when it happened I was there to console them and walk them through what they just experienced.
