First Loose Tooth

Joseph first loose tooth.
Came out to the car after school saying that his front bottom tooth was loose and sure enough it was. He claims he came loose when he bit the button on his glove but David and I have a feeling it was already loose and he just noticed it when he bit on the button.
Cannot believe that he is old enough to even be losing those teeth. I still feel like it was yesterday that they were all popping out of his gums. He got them so quickly as a baby. I wonder if he'll lose them just as fast.
