Aurore Petit’s books are thoroughly contemporary—they are designer must-haves yet full of emotion.

My Baby Sister Is a Diplodocus

In this eye-catching neon-bright picture book, a brother finds an inventive way to connect with his new baby sister through his love of dinosaurs.

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 baby sister—baby sister diplodocus.

My Baby Sister Is a Diplodocus is a new sibling story within the imaginative world of a toddler. We share a brother’s excitement then disappointment in his new baby sister. But his love of dinosaurs opens up a new path. By imagining her as a dinosaur, he connects with her, making room for everyone in the family.

Vivid contemporary illustrations and surprising perspectives complement a spare narrative. Affecting vignettes of this new family, with its little baby tucked up in the centre of the story, combine with graphic/comics elements in the storytelling as we share the emotion of each moment unfolding.
