The Littlest Inventor is a brilliantly colored picture book featuring a smart, sensitive boy with sensory issues. These issues make it challenging to experience something most of us have no problem with―i.e., a simple trip to the grocery store. However, by being self-aware, creative, and proactive, the littlest inventor succeeds in the very task he finds most difficult. He invents his own resources and tools to make the trip fun!

For those with sensory processing disorder (SPD), life can often be overwhelming. However, when equipped with knowledge to help ourselves and confidence to be ourselves, life becomes not just manageable, but enjoyable.

“There needs to be more emphasis on what a child can do instead of what he cannot do.” – Dr. Temple Grandin
