Clearwater -With her classmates all around her, the animated 5-year old in the plaid outfit can be seen on YouTube giving it her all at the Plumb Elementary School Christmas show in Clearwater.
If you look closely, you can see that Claire Koch is signing the words to the song.
"'Cuz my parents could understand," said Claire.
Claire's parents, Tom and Lori, are both deaf. Lori posted the video on Monday, and so far, more than a 1.7 million people have watched it.
