I'm starting with I'm Grumpy, because I think it's wonderful that Jennifer and Matthew have created a duology that focuses on understanding your emotions.
Cloud begins the book grumpy, and Jennifer and Matthew do a nice job of explaining just how Cloud got to this point - using beautiful, complex illustrations, especially for a board book. Though Cloud doesn't apologize for feeling grumpy, Cloud does learn how to interact with others who may not feel so grumpy.
With vibrant illustrations and short sentences, this is a charming book that's perfect for the burgeoning young reader.
