I absolutely hate pop up books. I can't handle the stress of me wanting to keep them looking nice, and my son wanting to use them. He is normally pretty careful, but lets be honest he is two, so some have had a lot of repairs. I hate pop up books with a passion, but that doesn't mean anything, anyone who wants to buy one for my son is still allowed.
(I have gotten over my play-doh phobias, marker phobias, paint phobias but not pop up books. That is not entirely true, the paints are still kept out of reach as is the play-doh, and he has never gotten to play with more than one color of play-doh at a time. But I've finally allowed him to keep his markers himself. I felt guilty because he hid them from me, so I couldn't take them away when he was done. He hasn't done anything bad with them to warrant me taking them away so now he gets to keep them.) My poor child his mother is psychotic. I can't help it, I don't like play-doh colors mixed, I am afraid of art mediums on the wall, and I hate bent pop up books.
