But what children's stories of a certain era are not essentially Christian tracts dressed up, bizarrely, in myth and legend? Hans Christian Andersen, the brothers Grimm, and so many other story-tellers until the 1950s promoted what were essentially Good vs Evil tales. Knights of the Round Table, Black Beauty, The Water Babies, on and on. My mother had a book of legends of the Rhine (translated into English!) and the stories were the same - dark towers, knights gallant, rescue of the innocent, punishment of the wicked. Various allegories, various authors, various presentations, but essentially based in a Christian ethos.
If you look religiously at 'The Babes in the Wood' it's an allegory about straying off the straight and narrow, becoming beguiled by the forbidden, and the consequences for doing so. 'Goldilocks and the Three Bears' - greed, selfishness, lack of compassion for others, and its results. 'Little Red Riding Hood' - sweet innocence is threatened, but the attacker (corrupting Satan) is overcome, and goodness and right (God) ultimately triumphs.
Even all the delightful Grey Rabbit tales and Beatrix Potter's works point to the rewards of diligence, duty, obedience, humility, kindness and care. No matter how put upon the 'nice' animals are by the 'nasty' animals (usually rodents, foxes, and wolves), good always triumphs (God always triumphs) in the end.
Nowadays, you could simply discard the hidden message and say that, in a far from boring way, they represent sensible advice that any society would not suffer to take in, regardless of personal belief, or non-belief.
