Anything she gets her hands on. I've just done in intricate jigsaw puzzle with superglue to put the wallpaper next to her bed back together. I've trimmed down ds's huge poster of the UK to remove all the little boxes of info round the edge because dd had ripped most of it off. Thankfully just the map part was ok and fits into a frame so she can;t do more damage. Any paper she can get she rips. All her craft she does now when she asks to get stuff out involves covering paper with stickers, ripping it into shreds and putting it back together which is fine but then it extends to the label on B&SIL's souveniers when we were at their house, the posters, the wallpaper, books, boxes, puzzle pieces. Today she was found biting chunks out of the foam american football sent as a present when ds2 was born.
She is 3, she just doesn't get that you don't break stuff. How do I get through to her? Or will it just pass? I don't remember ds1 having a phase like this. He got a little experimental when he was 4 or so but he stopped after breaking a couple of toys. I am bloody close to taking a pair of scissors to her beloved lions to sho her how it makes people feel when you break their stuff. Obviously i won't ever do that. I don't mind breaking stuff by accident or even the odd "what happens if I bend it this way" but the constant mindless shredding of stuff is making me see red.
