Indestructibles place Mary and her little lamb in Africa in a wordless presentation of the nursery rhyme which appears, for reference, on the back cover. Vivid, well-defined pictures encourage natural conversation between parent and baby. Recognizing pictures builds vocabulary and encourages storytelling that becomes more complex as babies develop language. Traditional nursery rhymes delight little ones, build memories, and serve as conversation starters. Asking questions and putting forth ideas enrich the storytelling experience, and as baby gains language skills, monologues become delightful conversations. Thin Tyvek-like pages allow babies to grasp, crumple, and turn pages without tearing and to chew without damaging the book.
