Hands down the best book I have found for teaching different feelings and how to handle them for young kids. We got this with our Timberdoodle kit and I’d recommend it to anyone and everyone. Our daughter was a late talker so this has really helped her with expressing how she is feeling and how she handles her feelings.
There is a wide variety of feelings in this book. Each has a short paragraph giving an example of the feeling. What I found amazing was after the explanation they have a question related to the feeling. It gave us a great intro to further discuss the feelings and a way to teach our daughter how she could act in different situations.
