The illustrations are colorful and fun.  The story allows the reader to read between the lines:  if one pays attention carefully to the reactions of the sideline characters, one realizes that the dragon being described by the main character falls more into the category of imaginary friend.  The story opens with a young boy helping his father build a crib, which happens to be decorated as a castle.  The opening line states, “If you help your dad build a castle, a dragon will move in.”  Throughout the book, a full understanding requires that the reader pay attention to both the pictures and the text to put all the pieces together.  The situation (new baby arriving) is one many young children will relate to, and while I’ve read many books that address the situation, not all of them offer something creative or fun to make them stand out.  This one does.
