It's been a challenge to me to figure out what's too much. If you let them, they will spend hours watching YouTube shorts, or tiktoks. I've removed YouTube from our TV for that reason. Also the devices are locked down using Google family, plus the screen pin code is only known by the parents. One of the most wholesome digital experiences I've seen is setting up a Minecraft server, and watching the kids have a build battle. You do need to set up grief prevention though, they will try to vandalize each other.

It is usually some 'set hours' of device time?

Also, wondering what was meant by wholesome digital experience (positive?) in going through setting up a server with your kids?
