This is a great work of literature disguised as a board book. Boynton uses children's fascination with animal sounds to great effect: the rhyme is strong and simple, without being nauseating in the way baby books often are, and bears endless repetition; and I think pictures are Boynton's best so far, clean and uncluttered. Our older children (aged 3) now 'read' it from memory to the baby. He in turn has proved an addict ever since he could crawl to the bookshelf to fetch it on his own. Fun for all, from babyhood up, but especially for those just learning to talk.
