I'm not advocating we work full weekends, but I'm not sure why I would not have a few hours for myself and do things that don't involve my kids. Some weekend's it would be work but other weekend's it might be something else, but it surely doesn't have to be 24/2 just kids kids?
Of course if you blink you miss them, it's not like you're in a cave across the world, you're probably literally in the next room staring at a screen for a couple hours after a heavy lunch while the kids play on their ps5. How's that weird.
