I recently read Captain Courage and the Fear Squishing Shoes by Stacey A. Marshall and loved it. As a kid I was a lot like Katie, who moved to a new school and felt afraid to talk to anyone. Her school principal turned into Captain Courage and destroyed her fear so she felt brave enough to speak out in class and all the kids loved what she shared.
If only real school principals had time to help individual students like Mr. Magico did.
The bright illustrations by Michele Morse portray the story wonderfully.
And, even though this is a fictional story, this morning I saw a video about scientific studies that show what Captain Courage did can actually work in real life for adults, too. The video is long, but if any grown-ups want to watch it, here's the link
But the delightful book is better for encouraging shy kids.
