She *is* smart. She's just DISGUSTING!
What changed my mind? Well, we got a toilet lock for the toilet. I thought the toilet water was safe. Alas. Not only did she defeat the toilet lock on her very first try, she pushed open both toilet lids (she didn't used to be able to do that) and then got herself a STRAW and drank out of the toilet WITH THE STRAW.
She is the grossest kid that I know!
Here's a picture of her eating mud. It's not as gross as what she was eating the other day out of the toilet, but the visual may help your imagination with that.
