I dont believe in Fairy Tales............But fairy tales, makes a child's imagination work, the critical thinking power-that is best in kids, improves.So, i dont think there is nothing wrong in reading fairy tales to kids..
Have you got a DOPler in your home? Something disappears but no-one has touched it only to reappear later in the origional place or somewhere so different you would never look for ot there? examples are keys, shoes, hairbrush, shampoo etc.
