Worry says what? is a great book to help children identify and give shape to the worry they can be encountering. Edwards creates a fuzzy worrier monster that will not scare children but help them to visualize the worry they go through as well as help them materialize and create a figure which they can focus the worry to and deal with it constructively.
Edwards shows environments and situations in which a child will encounter and gives them feedback on how to combat the whispers of worry. This book can help for a parent and child to talk about stress in a visual way that a child can understand. The only situation I would have liked to see is that worry happens to everyone. Maybe have the character realize that worry is a universal encounter and everyone goes through these doubts throughout their lives.
