One thing I've noticed about a lot of dating/married succesfull Children's book authors (like Dr. Seuss, Michael Ende and Dav Pilkey) is that in a lot of cases the woman tends to be significantly older (usually by eight years). I've often wondered the reason for this. Is it because they want a more maternal figure than a wife? Is it because like Ben Franklin they love MILFs? Or could it be an older figure is more impressed with their knowledge/prowess?
