I've always liked the David Wiesner book "Tuesday." It's a nearly wordless journey of a night frogs ride flying lily pads. It's beautiful and ignites the imagination. And like In the Night Kitchen it shows what goes on when kids have to be in bed. What really goes on? Not much. But there are a lot of kids who think there's a conspiracy to keep them from seeing the magic that happens. Santa, the Tooth Fairy, the Easter Bunny - these all come at night. Why not more things?
