My 3 year old fell in love with this book immediately. The rhyme and rhythm of the poem make this an excellent bedtime story with its almost song like effect. The illustrations are clear yet have such depth that my child will stare at each page for several minutes, picking out the many details. If your child had fun finding the mouse in "Good Night Moon", he will love looking for the mysterious creature that watches from the shadows as the story unfolds.Though the plot could be viewed as kind of scary, the immages are depicted in very gentle and innocent drawings that leave the reader with a sense of comfort, not fright.
