Don’t forget about your network. Kids have to do homework online so that has to be monitored early as soon as they get home that it’s done first or they will notoriously try to play online or text friends or watch YouTube videos or do anything to put off homework until right before bed and then demand extra time to stay up online to finish work. I recall as an honors student having a high level of homework and staying up some nights late to finish it but my work back then wasn’t assigned online to do like teachers do in Its Learning and other online sites where they post info about home work like the Remind mobile app either. So it’s hard to pull plug on all electronics cause you want them to finish online Google docs work if they have group assigned work for a group project and they have to prepare slides or stuff like PowerPoint slides we used to do.
I still use 9:30pm bedtime as cutoff but if they can show me they still are actively working to finish legitimate online work, I will let one of them stay up as long as they can to get it done. In High School, sometimes that might mean almost midnight but nothing later as they still have to get up by 7:00am. We are fortunate to live across the street from school which tardy bell rings at 7:45am and they are out by 3:00pm.
Get Comcast XFi mobile app. It can control all electronics individually like all laptops, xboxes, playstations, mobile phones, TV sets, desktops and laptops. Set up a profile for each person and assign all their electronics to each profile. Then at bedtime, you can go to your phone and pause all devices under each profile or pause only individual things if they still need Pc access to finish work. Kids are sneaky. They will grab earbuds and headphones and plug into their phones or PCs to watch videos or movies under covers or chat all night with friends. They will try to take phones devices into bathrooms too (not cool). You don’t need a nightly battle but just control over your router—no router on, no TV, no phone comes on and no Pc can work. Use your phone mobile XFINITY XFi app (don’t bother with taking up cell phones or grabbing game controllers every night).
