Great sensory resource
Format: Board book
I am a teacher and a developmental therapist. This book is great for sensory exposure. The kids really respond to the colors. I find that they gravitate to this book and are able to sit for longer and longer periods of time with books like these.

My grandsons favorite book.
Format: Board book
The pictures are large and easy to understand. I like all the different colors and that each number is a different color so we can review that as well as count. The flap at the end could stand to be of sturdier material since it’s lifted several times daily by a toddler. Otherwise great book.
