I Wonder If I'm Growing: A new picture book classic from Jon Klassen and world-renowned singer-songwriter, ages 3-6

A perfect picture book pairing and new classic from internationally beloved children's singer-songwriter Raffi and multi-award-winning illustrator Jon Klassen.

I wonder if I'm growing. A child is carrying this familiar childhood question with them during all the little moments of their day – waking up, looking out the window, in the mirror, at the breakfast table, in the car and in the bathtub – until that magic moment… HEY! He can reach the tap now! For the very first time today. And finally, we can actually see this kid’s mouth in the mirror – and the big smile that’s on it.

Based on one of Jon Klassen’s favourite songs by the singer-songwriter Raffi, this is an exciting picture book collaboration about a growing child impatient to be taller. Told with funny, feel-good text perfect for reading aloud alongside Jon Klassen's iconic illustrations, this hardback picture book is a guaranteed crowd-pleaser for storytimes.
