Gotcha. Here's my experience with tech and kids. When my kids were younger I set up one machine in the house that they could use to access the internet, and on that machine I ran a reverse proxy. They each had 10 websites I would verify and whitelist. They all could access whitelisted websites as I didn't filter it down to each kid, they just all got 10 sites I would allow, and if that was a problem we could have easily discussed it and modified the number. It was just an arbitrary starting point. Now my kids were fine with it, wife and step kids weren't fine with my level of restriction but whatever. It caused some arguments but my bio kids knew that's how it was going to be at my house.
I truly feel for parents today as it is much harder to lock things down and keep on top of things like this especially as their kids get older. Maybe I just think that they should use different ways to distract them at such early ages. I definitely don't pretend to have the answers to any of this, and can only go by my prior experience and feelings about the matter.
