My ODS was like this. His actual reading level was pretty much on average until the end of first grade. He preferred being read to and could comprehend books several grade levels higher. I wanted him to love books and reading so I gave him what he craved, more complex books that we read to him rather than forcing him to read boring simple books on his own (he did that at school). Eventually and quite suddenly his ability to decode and his fluency caught up to his comprehension. He was reading middle school level books by the spring of second grade. I say read whatever she wants you to read to her and don't worry about the nuts and bolts. That will come.
