"Caregivers will enjoy making this a bedtime read, and librarians will turn to this often for pajama storytimes. Young readers who love rebelling against bedtime rules will delight in seeing Sheepy’s evening escapades, and astute members of this crowd will notice his happy smile when he’s finally curled up in bed.  An entertaining tale sure to resonate with those on either side of the bedtime battle."--Kirkus reviews


"Children will begrudgingly drift to a dream land created by Cummins and Oswald. The title character, though appearing increasingly tired as the story goes on, is dead set against bedtime. . . . Rhyming and child-friendly vocabulary fill the tale with sleepy hour vibes. Oswald’s transitions between bright and muted color palettes create a definite difference between the need to go to bed and Sheepy’s denials. VERDICT This could easily end up a story hour favorite and an often checked-out new bedtime classic for not-so-tired kids and their very tired parents; this will especially work a spell on preschoolers." --School Library Journal


"His eyelids are already below half-mast, and his weary parents—each of whom totes a wide-eyed infant lamb in a front-facing carrier—insist that it’s bedtime. But Sleepy Sheepy, rendered by Oswald (the Food Group series) in fluffy, cloud-like textures, insists he’s anything but sleepy . . . But readers will discern that Sleepy Sheepy’s actions are more kicky than joyful; eventually, he lets out a big yawn, and soon, Cummins (Rock That Vote) writes, “His eyelids drooped. His shoulders stooped. His brain was pooped.” . . . even the most bedtime-resistant readers will respect his exhausted capitulation." --Publisher's Weekly
