“Hey, baby! Look at these things with wings.” Thus begins Flutter! Fly! with its thin Tyvek-like pages that allow babies to grasp, crumple, and turn pages without tearing and to chew without damaging the book. A wordless book with vivid, well-defined pictures, Flutter! Fly! encourages natural conversation between parent and baby. Recognizing pictures builds vocabulary and encourages storytelling that becomes more complex as babies develop language.
