At Least We Always Have Confetti For Parties

Isabelle has always liked tearing paper. Ever since she was big enough to get her hands on it, she has been shredding paper into tiny pieces - books, kleenex, anything she can rip, she will rip. And while it is annoying and destructive, I have always assumed she will grow out of it. She knows she is not supposed to tear pages out of books, and she is no longer allowed to have any paper in her room during nap times because it will always end up shredded. But I am beginning to wonder at what point do I start to worry that this habit has become a compulsion? Because she will literally rip ANYTHING if she is left alone with it she will rip it. She knows she is not supposed to, she will tell me that she won't rip anything, but then very next time she has some paper it is ripped. And of course, she is only three, so I'm not all freaked out or anything, but I'm beginning to get a little more concerned about it bcause she has started destroying all her art projects. She comes home from school so proud of her drawings and asks me to hang them on the wall in her room. And as long as she had books or other stuff in there they were fine. But now that I have taken all the books out of her room, she is taking down the art and tearing it up. Is she just sick of the pictures, or can she really not help herself? I certainly have not gone so far as to be worried about OCD or anything (if anyone has that it's Jack anyway), but how long should I just live with the issue before it really needs to be addressed? She doesn't really do anything else she knows she isn't supposed to do, but she will tear paper up in a second. I hope she grows out of this soon because keeping every type of paper away from her all the time is not realistic, and man I am sick of picking up scraps of paper everywhere.
