"PreS–These interactive books encourage readers to wake animals or soothe them to sleep by tickling them gently, petting their shells, singing a song, or tracing their tails. The layout and structure is consistent through both volumes. The majority of the text appears on the left page, and the ­animal is on the right, with the title ­repeated as a refrain. Animal names appear in bold. ­Animals include a hedgehog, cat, baby deer, and more. All look appropriately cuddly, with soft edges and no outlines. Backgrounds are a solid color that changes with each turn of the page. Sleep Tight features a ladybug on so many of the left pages, it feels like a purposeful inclusion, similar to Goldbug in Busy Town. These are kind, compassionate stories encourage gentle, loving touch. ­VERDICT A perfect read-aloud for a caregiver to share with a ­little one. ­Definitely add both of these titles." – School Library Journal
