A word about the Bob Books. I have mixed feelings about Bob. On the one hand, an early reader can feel proud at "reading a book" and thus motivate them to try more. On the other hand, they are pure nonsense. They are really no different than reading off flash cards.
As an avid reader myself, I prefer real literature; or at least books that tell an actual story. I have found that the Bob Books are fine for phonics practice, but "real" books are what motivate Helana and helps her feel a sense of accomplishment when she reads one of her sight words. Afterall, she watches me read "mama's books" and can tell I am not reading "Mat Sat. Sam sat." Monkey see, monkey do.
