M loves the rainbow magic books, too. But, she loves all books. She got "stuck" reading George macdonald "the princess and the goblin" last year (age 6). It was taking her ages to read it. I asked her one night what was going on and she said "I don't know. It feels like a long book" and I told her that it was actually shorter than what she had been reading. She paused for a bit and said "is it possible that I don't like this book? I mean, that's never happened before, I love all books... But maybe I don't like it?" She seemed traumatized to acknowledge it. smile So, she reads some books to feed her brain, and some books to feed her soul. This also meant that some popular fiction does not enter this house, because she will read whatever she picks up. Ahem. No Fifty Shades here!
