I'm really interested in what others do here
I'm pretty easy going with my kids access to tech (2 DS age 11 and 13 and step DD age 12)
As long as they get out and about for part of the day nor do some other activities I let them have their devices as much as they want
But I do take them all away when I go to bed.
They think this is very unreasonable
I'm worried if I don't take them away they'll be up all night looking at who knows that.
