A three-time Caldecott Honor winner (for Don’t Let the Pigeon Drive the Bus!, Knuffle Bunny, and Knuffle Bunny Too), he also won two Geisel Medals and two Geisel Honors for his Elephant and Piggie books. His books are perennial New York Times bestsellers, including Knuffle Bunny Free, Hooray for Amanda & Her Alligator!, and the Cat the Cat series.
