Brace yourself. It may have repercussions you have not yet pondered.
My kids and I enjoyed story time so much we saw no reason to quit when they could read the stories for themselves. So I began reading them things that were still above their competence.
My daughter was especially keen on this. After we finished The Hobbit, she (at 7) decided I should right away launch into the LOTR trilogy. Throat did suffer, especially when Merry and Pippin had long speeches, since I'd given them both counter tenor voices (I'm a bass), but the bonding value was incalculable.
Her reading skills raced on ahead, and by the time we finished (5 months later) she had secretly read ahead to find out how the story ended.
Diana's 37 now, still devouring novels at a prodigious clip, and by far my best (and toughest) beta reader.
