Jack also loves the anticipation of knowing what is coming on the next page. If he ever jumps ahead or back in a book, it is inevitably to the page just before the one he really wants to see and hear.
We only have a couple of pop-up/reveal books in the current repertoire. When Jack was really little, he pretty much tore these kinds of books apart. The reading of "Grandpa and Me" below is a fun little highlight reel of what it's like to read to our precocious boy.
