This book is based on the familiar game So Big or How Big is Baby? It uses repetition and imitation 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.
