This simple board book invites little ones to greet baby farm animals (including frog, bunny, and bee) with their corresponding sounds. The first double-page spread greets readers with a bright yellow smiling sun and the text "Hello, Sun. / Hello, Day. / Wake up, babies. / Time to play!" Each succeeding spread has a distinct, gently patterned background, with very brief text on the verso ("Hello Puppy! / Woof Woof"). Filling up the recto is a vibrant illustration of the baby animal's face, wide eyed and smiling, outlined in black. The final spread presents the face of a cute baby with chalky brown-gray skin, bright black eyes, and short black hair: "Goo Goo." Babies and toddlers will enjoy looking at the baby faces, animals and human, and repeating the sounds. A companion book, Goodnight Bear, has a similar pattern of text and illustrations, though the palette is suitably darker. The moon, surprisingly, has its eyes shut, and succeeding spreads depict an owlet, a baby bat, a baby hedgehog, and other familiar nocturnal baby animals, all wide-awake and smiling. The final spread depicts a cute baby with pale skin, blond hair, and closed eyes. It's not exactly original, but the execution, with familiar, appealing Cabrera illustrations, is attractive and perfect for the target audience.
