The Best Children's Books of the Year 2014, Bank Street College

"Cocca-Leffler's friendly mixed-media illustrations telegraph each child's emotions clearly, and her story underscores the idea that good and bad moods aren't mutually exclusive."--Publishers Weekly

"The situations his classmates describe are all easily relatable for preschoolers, and the bold, playful illustrations make the moods recognizable and the characters distinct."--Foreword Reviews

"It's refreshing to see that his classmates are supportive and help him to understand that mixed emotions are part of being a big brother. It's also refreshing that the children are encouraged to express their feelings, both positive and negative."--School Library Journal

"Both the text and the bright, expressive illustrations focus squarely on Theo and his friends, with a developmentally appropriate, low priority on the baby...Cocca-Leffler once again demonstrates her understanding of small children and the complexities of their emotions."--Kirkus Reviews

"The new-brother storyline adds a nice framework to the typical grocery list of feelings, and the storyline helpfully results in each mood's getting more than one possible motivation."--The Bulletin of the Center for Children's Books
