Query: Smart and charming!

This is a delightful book! Dr. Maas weaves his expertise about good sleep habits into a story to which we can all relate, using rythm and rhyme that my five-year-old daughter loves. The illustrations are amusing and the sing-along CD is catchy, making this a book for her to enjoy on her own in between our "storytimes". Thank you for offering a fun, intelligent and applicable book!
