Love from the Very Hungry Caterpillar by Eric Carle

A very short book that utilizes figurative language to express love.  The narrator is the "very hungry caterpillar'.  Although this book is short and the audience would seem to be babies/toddlers/preschoolers, I doubt they will really understand being "the apple of my eye", "the bee's knees", "you make the stars sparkle", "you make the birds sing" and "you make my heart flutter".  Maybe it would provide an opportunity to discuss idioms?
