A brother finds an inventive way to reconcile with his new baby sister through his love of dinosaurs in this eye-catching, neon-bright picture book. My new baby sister comes home. But babies don't drink milk, don't ride a bicycle, don't play my games. Do I like being a big brother? No! Roooarr! I stomp around and go to sleep in my T-Rex onesie. In the morning, I take another look at little sister--little sister diplodocus. My Baby Sister Is a Diplodocus is a sibling story that mirrors the imaginative world of a toddler. By fully inhabiting his dinosaur world, a brother reconciles with his baby sister, finding room for everyone in the family. Vivid contemporary illustrations and surprising perspectives complement a spare narrative as we share the emotion of each moment unfolding.
