About the Book Tona has BIG feelings. There are many things in her day that she does not want to do. Leave the park? No thanks. Share with her sister? Hard pass. And there, to help her executive function is SAM, the little messenger who travels between her “upstairs” and “downstairs” brain. When Tona is distressed, SAM steps down. When mom offers choices, comfort, or understanding, SAM steps up. This groundbreaking book gives toddlers insight into their own brains, and helps parents to understand what’s going on in their own little monster’s noggin.
