The first time Avery lost a tooth she was real quiet all day, and finally broke down crying right before bed, saying she didn't want the tooth fairy to come into her room while she was sleeping.
That's fine with me, since I usually forget to "unlock the door" so the tooth fairy can come anyways!
The next time she lost a tooth, it just "disappeared" and we don't even know where it went. I think she's getting rid of the evidence just in case the tooth fairy decides to come and look for them.
She's not too crazy about Santa either, for the same reason. On Christmas Eve, we have to lock her door because she's uncomfortable with the idea of some stranger coming into our house during the night and watching her sleep. Just leave the gifts under the tree please, but don't come into my room!!
