3 years & up. First published in 1963, the "simplest Seuss for youngest use" remains a perennial favorite when it comes to teaching kids to read. Dr. Seuss creates uncomplicated, monosyllabic rhymes to foster learning and inspire children to read. See Red and Ned and Ted and Ed in a bed. And giggle as Pat sits on a hat and on a cat and on a bat . . . but a cactus? Pat must NOT sit on that! The illustrations are wild and the language is delightfully silly.
