There are lots of big emotions in my household with my young kiddos. One of them struggles to even read about other kids having emotions because it evokes so much discomfort for him. These were perfect. He seemed to appreciate all the stories (even though he listened to half the book from a room away when the characters where struggling to keep their emotions in check). He loved the end of the book that has teaching lessons for kids to discuss with parents the tips on handling the emotions. His younger brother loved the stories (he seemed indifferent to the lessons). Highly recommend for all kids, but even more so for the kids who struggle with regulation.
