This is not simply a story about a frog and a prince. A story about a frog would be biological. A story about a prince would be historical. But a story about a frog-prince is magical, and therein lies all the difference. – Jane Yolen, Touch Magic: Fantasy, Faerie and Folklore in the Literature of Child
When the first baby laughed for the first time, the laugh broke into a thousand pieces and they all went skipping about, and that was the beginning of fairies. And now when every new baby is born its first laugh becomes a fairy. So there ought to be one fairy for every boy or girl. – James Barrie
