My idea of an interactive childrens book would be like a mix of choose your own adventure + scribblenauts.
Giving the child the chance to first set up the main character with any attributes they like, having a storyline that they can follow but allowing them to try and progress through some problems themselves with some puzzle solving techniques. (And adjusting the outcome based on their choices to solve the problems)
