Spaghetti is yummy, but worms — and blue crayons, and sand, and other things too gross to mention — are definitely yucky when tasted. Amiably illustrated in a bright, graphic style, Leslie Patricelli’s spirited board book Yummy Yucky stars an obliging, bald, and very expressive baby who acts out each pair of opposites with comically dramatic effect. Now available in a dual Spanish-English edition!
