8Caldecott Honor artist David Shannon is back with an all-new, original board book that lets young readers see what the star of the bestselling No, David! books did as a troublemaking toddler.

Oops! Did somebody make a mess?! Join David as he finds himself in a few sticky situations, and learn his five favorite words along the way. From throwing a ball to riding a tricycle to taking a bath, David sometimes has a little too much fun. But he knows there's nothing better than cuddling with Mama at the end of a busy and exciting day. With the same irresistible humor and vibrant style as his award-winning No, David! books, David Shannon takes us back to the "early years" of his most beloved character. Perfect for beginning readers as well as for the youngest children!
