“How do you make a baby smile? Grin like Papa Crocodile.” The animal kingdom comes to the rescue of a baby’s doting older sister in this simple, rhyming bedtime story that offers numerous tips on how to amuse fussy youngsters of all species. Each oversized, color-drenched double-page spread features an animal parent’s loving attempt to keep baby happy. Mama Elephant wiggles an ear to make her not-very-wee one smile, Daddy Deer shakes his horns for his spotted fawn and Papa Giraffe twists his neck to delight his long-lashed cutie pie. In the end, the baby’s human sister tickles her brother under his chin, and when he yawns, tucks him into bed with his menagerie, cleverly composed of stuffed versions of the nine animals previously pictured. The friendly artwork, all affectionate animal eyes and big animal smiles, is a baby-pleasing combination of rich, saturated color, bold black lines and artful compositions. A cheerful, if not groundbreaking, offering for the very youngest baboons. (Picture book. 1-3)
