This is kind of cheating, but I did read them all today!
I was dusting and ran across this little set of books, which were a gift to me from my Aunt Betty when I was not quite 4 years old. They're as charming as ever, and reminded me that one of the four introduced me to such things as idioms that I was too literal minded to understand. Like eyes bigger than one's stomach. When in the picture Aaron's eyes are clearly normal alligator eye size and his stomach is normal size, too.
P.D. Eastman is the author of many familiar books for little ones, such as Go, Dog, Go! and Are You My Mother?
