And then when kids cannot conform to this it's labeled ADD and ADHD (I know that these are also real diseases, but I do wonder how much of it is perhaps caused by schedules described in your comment). Do you (parents in general) think this is normal and good for a child? I had thought homeschooling was lunatic, but if this is the alternative, I can see why people would choose it. In Hungary in high school we had 45 min classes and 15 min breaks for the first 3 breaks, and then 10 min breaks. We had usually 7 classes per day, so school went from 8:00 to 14:30, usually. Then lunch if you want. In primary school we had a break where it was mandatory to go down to the schoolyard to be outside in the fresh air (but then do whatever you want).
