I think this book is a great way to show children that not every sport is boy or girl. For example, in the story, Billie wants to stomp around and be a troll and Jack wants to be a graceful butterfly. At the end of the story, Jack admits that he loves ballet and Billie loves soccer. What this book is trying to accomplish is saying that girls can do boys things, just like boys can do girl things. ( )

A great book for beginning readers that challenges gender sterotypes in a very affirming way. ( )
