Annabella is a vibrant, active, engaged little girl who is so busy during her days in school and so full of ideas when she comes home that she finds it hard to settle down and go to sleep every night. Until, that is, her mother thinks up an ingenious method of calming down her little girl and helping her to drift into a delicious and peaceful slumber. It's so ingenious, in fact, that it will help grown-ups get to sleep as well.
