Pigs Have Piglets

Readers learn the names of seven animal babies in one of five titles in the Little Bug Books series from Animalia creator Base. On each spread, an adult animal is pictured against a spare backdrop; pulling the right-hand edges allows the full scenes to expand, uncovering the animals’ mates and offspring (“Horses have... foals”). Base’s handsome portraits lend dignity and grace to each animal (even the pigs in their muddy, mucky pen), and a seek-and-find challenge involving a tiny hidden bug brings another engaging element to a nicely designed jaunt into the animal kingdom. Simultaneously available: Birds Fly, Herd of Elephants, Monkeys Live in Trees, and Starfish Are Pointy. Up to age 5. (Oct.)
