ea. vol: unpaged. (Great Big Board Bks.). Random. 1986. BD $3.95. PreS These six titleslarge, splashy, practically indestructible books for toddlerscater to that audience of preschoolers who may still be rough on paper pages. Anna Bear's First Winter is a delightful book that tells of a bear's first experience with hibernation. It is enhanced by softly colored illustrations of the bears and of interiors of their country home and setting. Jamie Goes on an Airplane and Katharine Goes to Nursery School are reassuring books for two situations that can cause young children anxiety. Full-color photographs accompany these books. The Little Chick is a fairly humdrum story about a wayward barnyard chicken. It is not as fresh as the other animal stories in this series, but the lush, colorful drawings will sustain interest. Good Night, Little Rabbit is a bedtime tale in which the little bunny reminds his mom of all of the things she forgot, from a glass of water to a goodnight kiss. The differences between owning a live pet and a stuffed one and the responsibilities and joys of the former are deftly told in The New Puppy. All in all, these oversized board books are lots of fun and will be an excellent purchase for toddler collections. Janet E. Fricker, formerly at Phillipsburg Free Public Library, N.J.
