These days, returning to the classroom seems to involve more homework for parents than for students. Enough of the arms race of parties, and get-togethers, and “fun” activities that involve the parents as much as the children. But when they’re at school, can they be at school without parental involvement, save for a spring recital? Over the years, very little of the parental stress I’ve experienced around the return to school is about academics. Add that to the back-to-school prep list, which already runs the average American family about $900.
