Say you were a guardian or parent and get to decide when a child can get a phone or use a computer and get internet with it. If you wish you can also install software and change router settings to what you see fit.
Some parents decide to forbid the internet completely, others are more relaxed. Some go the helicopter route, and some do not care whatsoever what their kid does online.
What is your policy on letting a child use the internet?
I’d wait until they’re older, 7-8 years of age at least. Then I’d make sure they learn how it functions in some capacity and not just operating it mindlessly.
No social media at all. Heavily curated Youtube, and honestly at the end of the day I’d rather them play outside under supervision than spend all day online. The internet as it is does not go well with developing minds.
