Watch it and weep – for this is the cutest Christmas school concert you will ever see.
Claire Koch can be seen singing as she uses finger spelling and signing to match the lyrics of popular carols such as Rudolph the Red Nosed Reindeer and Jingle Bells.
Proud mum Lori, who is hearing impaired, posted the video after reading about claims that a sign language interpreter at the Nelson Mandela memorial was a fake.
In a tweet, Lori said: "My five-year-old signed even better for her deaf parents in an xmas show."
The video quickly went viral and has had 3 million hits as viewers watch little Claire enthusiastically signing to a series of Christmas songs.
During the video, the other children were doing hand actions for the songs, but Claire stood out from the crowd as she used American Sign Language.
