Leo the Late Bloomer by Robert Kraus and Jose Aruego

Leo the tiger cub isn’t reading, or writing, or drawing, or even speaking, and his father is concerned that something is wrong with his son. But Leo’s mother isn’t. She knows her son will do all those things, and more, when he’s ready. The book is an easy read and can be used to help reassure children who find themselves behind developmentally compared to their same-age peers. It also touches upon family acceptance and support. Every child wants and needs encouragement from their parents and this story conveys the message to both children and parents that it is "okay" to be different.
