Book age level is listed 2 - 6 years old, but I would recommend this book for 2 - 4 years old. My son just turned 6 and was given this book as a birthday gift and it was definitely more geared for a younger child.
However, it is an excellent interactive book that allows the child to get involved.
My almost-three- year-old daughter loves this book! It's easy to read, funny, and the pictures are simple and not distracting. She enjoys saying, "No you mayn't drive the bus!" to the pigeon. Highly recommended!
