I would like to give the kids a time limit as to their WiFi usage per day. I know you can give them a window. I know you can pause their usage. I want to let them choose how they want to spend their time and shut off after a certain amount of time. Doesn't matter whether they use it first thing or at the end if the night. That way it is fair between kids, rather than up to me to pause when I feel they've had enough. And then I inadvertently gave one kid more time than the other.
Shaw Blue Curve has it if you want to check it out.
