Edwina, the Dinosaur Who Didn't Know She Was Extinct by Mo Willems. The story is about a dinosaur named Edwina that wins her town over with overflowing kindness and cookies. She is loved by all, except for Reginald Von Hoobie-Doobie, who is on a mission to convince the town that ALL dinosaurs are extinct, including Edwina. Reginald tries a variety of tactics, but ultimately, Edwina wins him over with her kindness.
I am not sure why we don't own this book, but it is a library favorite. Edwina is an adorable dinosaur that is loved by my daughters the way that I grew up loving Danny the Dinosaur. The story is silly and fun, which was a much needed after reading the Enemy the night before. As with all Mo Willems books, Edwina is entertaining enough to keep the attention of my almost one year old baby, while receiving the "not boring" stamp from my 6 year old. There are not many books that can keep this range of readers attentive and listening.
