None of my kids would read Bob books. They're not just boring, the illustrations are terrible line drawings.
Some classic Seuss titles like Hop on Pop are good for new readers. My daughter really liked The Big Fat Cow that Goes Kapok as one of her early readers. There was also a collection of books with good illustrations that we liked-- I can't remember it now-- but a good book store will have a lot of fun titles for an emerging reader.
FWIW, 2 1/2 was when my oldest started reading words all over town. He was barely two when he read "CAT" on some construction equipment, and realized there were words everywhere he looked. It was so fun to see him figure that out. He could read books by 3 1/2, and started on Magic Treehouse by his 4th birthday. You probably need to get a library card for him soon!
