This makes sense but I don't think it works for me. I get irritable when I'm trying to do something like the activities you listed, if I can't focus on what I'm doing without interruption, and then that's bad for everyone, both the interruptee and the interruptor. This seems to be a personality thing (disorder?), my wife seems to be able to switch back and forth from working to parenting without it affecting her ability to perform on either task.
