"How big is baby ostrich? SOOO BIG!" Young children will love lifting the flaps to find out just how big each animal can be. The text is simple: "How big is baby...? SOOO BIG!" Lift the flap to see giraffes, owls, and snakes stretching and leaping to their fullest extent to impress the world with their size. The final page will be the favorite one, of course, as the question changes to "How big are YOU?" and a fold-out 22- to 48-inch ruler is displayed to be detached and mounted on the wall for kids to determine exactly how tall they really are. Charming illustrations, big and small, by beloved artist Dan Yaccarino (Circle Dogs, Zoom! Zoom! Zoom! I"m Off to the Moon!), delight the eye with their warm colors and personality, while the playful concept will surely appeal to every tot who dreams of growing tall and strong.
