Children's Literature

I am reading the Chronicles of Narnia right now, and from what CS Lewis has to say about children's literature I find fascinating. As CS Lewis himself says: "I am almost inclined to set up a canon that a children's story which is enjoyed only by children is a bad story." The fear of childishness and desire to be very grown up resound in our culture today, I believe. Most people wish to be so grown up and stand up for what they think is right and blah blah blah. When others seem to enjoy things that children also enjoy, it seems to be looked down upon and immature. What do they define maturity as? They teach children in literature morals and not stories. As CS Lewis explains: "Since it is so likely that they will meet cruel enemies, let them at least have heard of brave knights."
I like what Singer says that when literature for adults has gone to pieces, children's literature will be the last of storytelling, logic, faith in family and God and in real humanism. Children's literature seems to bring up the eternal questions and hard questions in life as opposed to adult literature.
