DD3 has gone through two phases of wanting to read everything herself. As a baby, she couldn't get enough of being read to, but then when she started memorizing books she just wanted to recite. I would sit there holding the book while she "read" and only help when asked. She would get so mad if I would try to read it myself or (heaven forbid) correct her. It was pretty agonizing, actually.

Then when she started really reading, she did the same thing, even with books that were clearly above her comfort level. She never wanted help. That was the time the "We Both Read" series saved my sanity--because she was willing to follow the rules and just read her part. I think in part because I took it very easy and didn't push at all, she got through both phases with relative ease.
