If you have a cool mist humidifier, where do you put it?! We tried it out this weekend and placed it near LO's crib, on a box about 2 feet off the ground, but it seemed to wet the carpet beneath quite a lot. I am nervous to place it on the bookshelf, even on a towel, because I am concerned that it might wet the books or even the artwork on the wall.

Help, please!
