So Big! (Sesame Street) (Sesame Beginnings)

This book is based on the familiar game So Big or How Big is Baby? Using repetition and imitation, it ends with a triumphant finale in which the parent and child answer the question "how big is baby?" by announcing : Sooooo big! The book features Baby Elmo and a big pop-up of Elmo with his arms spread wide across two pages at the end.
