Hi, I am curious, is your daughter out-going? You say she only does this at school. First off where's the supervision where a first grader can cut her clothes with obviously sharp sizzors at school?! anyway, My daughter was adventurous, which lead into fearlessness, she started out with the most curious behaviors, She had to smell every page in a book before being able to turn the page. Cutting her hair, glueing her blankets together! So I understand the frustration. Kids are curious, they can become bored, they want to be different, they even probably at that age have no realization on Why they would do these things, it gets in their head..and they do it. I am telling you about my daughter who is now 16, all those Little quirks my daughter had, I chalked up to being a kid. I even talked to my doctor about it, and he said she would out grow them, well I don't want to alarm you because she may just do that, however my daughter did not. She still smells everything, pages of books, a new shirt,etc...she also developed new "quirks" not being able to put her feet on the floor when sitting on her bed, having to have everything in her room in the "correct" spot, she was evaluated by a psychiatrist, and has O.C.D obsesive compulsive disorder, which I now know she has had since birth. The best thing I think is to let your doctor be aware of what she is doing, and keep track of any new "incedences" she may develop, It can help you with any future questions a doctor may ask, if your keeping track through the years you will get your answer, if there aren't any new ones, or re-occurring ones, then she out grew it, if you start seeing a patern make your doctor aware of it right away. It could be something as simple as she is creative! and wants to express it that way! Good-luck!
