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.
