This stunning collaboration between a children's librarian and an NBA-player-turned-watercolor-artist introduces readers to a collection of baby animals doing what comes naturally--nursing. The luminous illustrations and lyrical text give children a glimpse into the worlds of 13 different mammal babies. Compelling childhood facts broaden the reader's knowledge about each species. Facts include: newborn bats consume their own weight in milk every day, and polar bear cubs are so small that they fit between the toes on their mama's paw. The overarching theme of breastfeeding inspires conversations about parenting, biology, habitats, survival, and more, making this book an engaging choice for young children as well as elementary school readers.
