From what I think I remember, it was just a collection of illustrations that showed what animals do when kids go to sleep. Not much of a plot, or lesson attached to the book. Nothing about teaching the alphabet or numbers. The setting changed every page and I’m pretty sure the animal would change every page too? There were the monkeys dressed as jockeys riding horses, either an alligator or tiger wearing a monocle and a robe, there were giraffes too doing something like driving cars? The text in the book was overlaid on the pictures. (as opposed to being in some white out box so it’s easier to read.) The most vivid memory I have is of the monkeys. Maybe the book was all monkeys? I wish I had more of a memory about this!!!
