We don't have that specific book but I can assure you that the only thing saving flap books in our house is that he is more interested in his touch and feel books right now.
Try clear packing tape on the outside of the flap, and regular clear tape on the inside of the flap. This is how I repair books in my classroom (I've found middle-schoolers to be just as hard on books as almost-toddlers).
