My Day is Ruined! by Bryan Smith
Continuing the topic of meltdowns, sometimes children with autism react to a negative event with more negativity. This feedback loop builds on itself until a meltdown occurs. In this book, the main character Braden has a seriously negative event. He learns about flexible thinking and how not to descend into a downward spiral of negativity, potentially teaching your child the same lesson.
