Busy Farm

Readers can push and pull slides to explore cheery if generic outdoor farm scenes in this addition to the Busy Books series. A question prompts readers to slide open a blue barn door where cows munch on hay (“Who’s that hiding in the barn?”), and a golden-haired boy brings buckets of slop for two pigs that have “just popped up to say hello!” Children should enjoy picking out details and the many animals that fill each spread. Up to age 3. (Apr.)
