Text Combined with Illustrations Make a Moving Story
This story can be understood on many different levels. Very young children can relate to the little boy's frustrations and feel empathy for him. They can vicariously feel his joy at the end. With adult discussion, they can begin and continue to grow in understanding all the other levels of interest in the text and illustrations as the book is read and reread each Christmas season.
