Here's my thoughts. > - What fraction of their online time should I sit with them? I try to spend any time I'm not doing something like housework or whatever with my kid. But ultimately (and you're going to hear this repeated) I ask her if I can join. I will state "ok I've finished my chores can I come and hang out with you?" She usually says yes. But I make sure to emphasize that I was doing chores as to give context and to also normalise the idea that when you do chores there's no tv or anything else. (music is fine) > - Do I play all video games with them or should they have some of "their own"? I let my daughter drive this... Almost always she wants me to play a multiplayer game with me. But about 20% or more she wants to play something by herself. So I give her that space. > - Do I give them the ability to do online purchases? Yes and No... We have a calendar on the wall, and every night before bed we do a ritual.. if she was a good girl she gets to color in the day green, if she wasn't good, then she colors it in red. If there's less than 5 red days then she can chose something to have... Last month was a pokemon game for her switch. That said... I have setup our online consoles so if she wants to buy something it sends me a message, and I approve it. This never happens, as I do the purchasing. But it's an option you can consider. Finally on our Xbox, Game pass is amazing.. she knows if she sees something in game pass she's free to download it and play.. > - Do I allow them to use up all of their money even as a mistake, or do I set up a limit? Depends on the age of the kid. If they understand the idea of money, you should probably setup goal oriented systems.. so do X and get $Y, it's important for them to learn how to earn money, and the value of money. If they are too young to understand money.. then a behaviour based system such as my red day green day calendar system. > - Do I limit their "screen time" (hate that term) or will that prevent them from interacting with their friends in the way they would want to? No, screen time is a stupid fear a bunch of people have. It's just the next dumb panic. Our grandparents had it when our parents were put in front of the TV. I'm guessing if you go back far enough there was probably panics about kids sitting in front of the radio. Screen time is dumb. However the real issue is what they are doing.. There should be some educational component.... BUT remember that everyone needs downtime.. you cannot expect your kid to go 100% education all the time....think about us at work, we need to browse the web or table tennis or whatever to have a mental break. So do kids.
