Books with title Baby Happy Baby Sad

Preschool kids won't know what a "lenticular" panel is (parents probably won't know, either)--but everybody will have fun seeing how it works! Move this book slightly, changing your angle of vision in relation to the cover, and the panel presents first one picture, then another! Keep varying that angle of vision and the picture keeps changing! This big board book has an inset lenticular panel that shows a clever little girl. Every illustrated board page has a rectangular cut-out to accommodate the panel and to serve as a words-and-pictures frame around it. In Happy or Sad?, the little girl's face changes from happy to sad. Kids who open this Making Faces book to any two-page spread will find a question, and its answer will make the little girl either happy or sad. Kids can move the book so that the little girl in the panel smiles or frowns. (Ages 3-5)
