Class group chat runs past 11 and my son feels he must reply instantly
My elder son is 13. His class has a group chat used for homework questions, project coordination and a steady stream of jokes and stickers. It runs until well after 11. The jokes are not the problem. He says that if someone asks about homework and he doesn't reply within a few minutes, he becomes "that guy". So the phone stays next to him through dinner and study time. I would like to set a household boundary, but I don't want to cut him off from the one channel the class uses to coordinate. Do schools expect children to be on these groups at all? How have others handled the evening hours?
