OH we liked Frog and Toad and the Henry and Mudge but DS read the first one or two, his reading level jumped and he was on to other things whereas I know kids who read every single Henry and Mudge etc. My son only ever read the first few of those books like oh can't recall, the one about the boy detective ... he never devoured an entire series like most kids I know...he would just jump to the next level and move on.
