What Does Baby Do? encourages small children to physically interact by imitating the behavior of the baby on the page. When Daddy leaves for work, baby waves bye-bye. When Grandma and Grandpa leave, baby throws a kiss. With every lift of the oversized flaps, little ones get to show off their understanding of words and actions and expand their memory. This book encourages understanding of words and actions, memory development, matching words and meanings, parent-child relationships, and imitation."
