In her introduction, Jane Yolen describes the lap as “a kind of schoolroom” where lessons learned are “learned forever.” With that in mind, she offers an impressive array of familiar and less well-known games, rhymes, and songs for adults to share with babies and toddlers. Each activity includes a description of its historical origin, plus brief instructions on how to use the song or game with children. Musical arrangements for piano and guitar are provided when appropriate. Will Hellenbrand’s brightly hued pigs decorate the pages with humorous charm, and a CD is included. (Ages birth–3)
