School is back in session. (Can we get a hallelujah?)Here are seven new picture books to keep young brains buzzing after hours.The Bippolo Seed and Other Lost Stories, by Dr. SeussA long-forgotten magazine series from the ’40s and ’50s gives us this treasure trove of tales. Seven newish stories will delight young (your kiddo) and old (yes, you) alike with their unmistakable Dr. Seuss rhythm and wit.Pirates & Princesses, by Jill Kargman & Sadie Kargman, illustrated by Christine DavenierThe chick-lit author teamed up with her own chick — er, daughter — to pen this coming-of-kindergarten fable about the gender divide on the playground.Marshall Armstrong Is New to Our School, by David MackintoshA back-to-school story about a new pupil teaches one of literature’s more important lessons: Never judge a book by its cover.ZooZical, by Judy Sierra, illustrated by Marc BrownWith spirited, hey-kids-let’s-put-on-a-show energy and singsong text, this narrative explains how a pack of animals beats the winter doldrums by pulling together a musical. Think Glee with monkeys and hippos.Spin, by Ido VaginskyDie-cut animals magically transform before your eyes in this visual delight. A cow twirls into an owl, a frog flips into a moose, and your toddler turns into a fan.Everything I Need to Know Before I’m Five, by Valorie FisherConsider this book a photographic syllabus of your preschooler’s curriculum. Images of retro blocks, tiny collectibles, dolls, and figurines are used to review everything from the ABCs and 123s to opposites, shapes, and colors.Little Owl’s Night, by Divya SrinivasanThe illustrator’s debut children’s book turns a traditional bedtime tale on its head. Just as everyone else rises with the sun, the little owl turns in — hopefully inspiring yours to do the same.The end.Photos: Courtesy of Random House; Courtesy of Penguin Group; Courtesy of Marc BrownStill reading?
