age 7+ Story of boy on the spectrum explores feelings, challenges. Parents need to know that Bat and the Waiting Game is the second installment in Elana K. Arnold's Bat series, and it looks a little more intently into the life and times of a boy on the autism spectrum. When Bat gets triggered by things he cannot control, he reacts physically by flapping his arms, standing on the balls of his feet, sometimes shaking his head back and forth.
