How Paxton lost his tooth

He's lost three now... his bottom two, and now his top front. It was loose for awhile, but wasn't quite ready to come out on its own. He inadvertently helped it along. We'd just gotten back from getting their Halloween costumes, and in his excitement to try his on he accidentally kneed himself in the face and knocked it right out. From the look on his face, I could tell he wasn't sure if he should laugh or cry. He chose the former. :)
