Hi E.,
I was just at my SIL's house and she had these very neat LED nightlights that changed colors. It would fade into red, then blue, then green, etc. They don't let off a lot of light and when they dim, it's quite dark. But, what I was thinking is that you could get 1 or 2 of them and introduce them to your daughter as "protective lights" or something similar (Maybe each color protects her from something she is afraid of). I think that they are so new and neat that she may just buy into it. I plan on getting some for my daughter's room (10 month old) so that she can enjoy the different colors as she goes to bed.
Good luck!
