Little girls and fairy tale princesses

Is it okay for a young Christian girl to look up to the "Disney Princesses" – for example, Cinderella, Snow White, Jasmine, Belle, and Mulan? My daughter is so infatuated with these characters that she has covered the walls of her room with their pictures. This makes me nervous since I'm not sure how it all lines up with truly biblical ideas of femininity and godly womanhood. What's more, I don't think it's healthy for her to go through life waiting for "Prince Charming" to come along and sweep her off her feet. What do you think?
