My son strongly disliked Bob books, as he would not read anything that didn't have real plot or more sophisticated humor. Basically, if I thought it was boring, he thought it was boring and didn't want to bother. There are some early reader books out there that fit the bill, but not many--AT ALL! I think it's one reason my son was not an early reader--he would just rather I read him things that were really interesting. He did like some of the Brand New Readers series, especially the books with Worm as the main character--they are quite funny. He also adored the Elephant and Piggy books (by Mo Willems) when he was slightly more advanced. My son was not one with a high sight word vocabulary early on, but he still loathed the Bob books b/c he just didn't find them entertaining.
