She discovered it last night. And after a couple years of Luke insisting that his teeth are loose just a little bit (which means not at all), I took the opportunity to check it out. Turns out, she has a legitimately loose tooth and she cannot stop touching it now. It's precious and she is so proud. She even asked if we could call Luke on his vacation and tell him that she has a loose tooth. And, convinced that she was going to lose the tooth last night, she asked for an apple.
We are still waiting. She's so adorably excited!
