When I got home Thursday night, Isabel had some exciting news for me: "I have a loose tooth!" I was stunned. In my mind, my baby girl is too young for such a monumental milestone. My eyes actually got a little watery but I kept it together for her sake. Lucky girl gets to show off the hole in her mouth on the rapidly approaching first day of kindergarten. Now the tooth fairy has some serious thinking to do... how much is a first tooth worth?
