Hungry?

I checked on the boys when they went to wash their hands, and was just in time to catch Louis stuffing paper towels into his mouth as fast as he could. I said, "Louis!" shocked, of course, that he was eating paper towels. He froze and looked at me with an incredibly guilty look on his face, as though to say, "Ah, man! Just a few more minutes and I would have gotten it down!" He just stood there looking at me with his mouth full, so I made him take the towels out of his mouth and throw them away. He looked incredibly disappointed - as he pulled three or four paper towels (slimy and drooly) out of his mouth. Since then, I've caught him eating paper cups and crayons. Either he has a serious oral fixation or he's not getting the minerals he needs. Something's not right. :)
