What is with You?

I swear I have one of the craziest kids ever. At three she still is putting stuff in her mouth and I totally don't get it at all! It's like she rebels by going backwards or something. The other day I found her with one of my mom's empty anti wrinkle creams and she had tried to get out what she could and ate it. All I could do is ask her what her problem is because she totally knows better! Not only that but the stuff was really perfumed so I can't imagine what made her even want to put that in her mouth. It is possible that she tried to use it like lip gloss or something but still, YUCK!
