She lost a tooth

How is it that she is already loosing teeth. It seems like she just go them. A couple of months ago when Kaitlyn went to the Dentist he told me that her two bottom teeth were loose. I was shocked and surprised by this. How could my little Kaitlyn have any loose teeth. She is way to little for a hole in her mouth. A couple of weeks later the tooth started to become more and more loose. Every time that I offered to pull it out she of coarse refused. But the more loose it became the more she complained when she chewed anything in her mouth. So one day while eating dinner she was complaining about her sore tooth while complaining about having to finish her dinner. So I made her a deal. I told her if she would let me pull her tooth out she wouldn't have to finish her dinner. And of coarse she jumped at the deal. There was hardly any pulling on that tooth and it was out. A few tears and a bloody tissue later she had her tooth in her hand. And then the excitement for the tooth fairy began. Of coarse the tooth fairy came that night and left her a whole dollar. The other tooth is becoming looser by the day and I am just waiting to pull it when Kaitlyn doesn't want to finish her dinner
