The girls and I had recently read One Morning in Maine by Robert McCloskey which is a lovely, slow-paced book about one girl's adventure with her first lost tooth. Mary loved the book but, weeks later, became somewhat obsessed with her own first loose tooth. She feared she would swallow it or that it would fall out in her sleep. She was not certain she liked the idea of the Tooth Fairy.
Finally, the tooth came out and she is much happier. She now shows everyone she meets the hole in her mouth and tells them that she is officially a "big girl". Here is a photo of her new smile, if you can see past the crazy hairdo (not sure what's going on with that--let's pretend she had just woken up that day :).
The tooth next to the first is also loose and she is hoping it falls out soon. She decided she liked the Tooth Fairy when she realized that she would get some money and a letter from her. :)
