Little William was captured strutting his stuff to the tune Jingle Bell Rock last week at Duxbury's Garden Centre in Preston.
His dancing delighted other shoppers who can be heard applauding and cheering the cheeky two-year-old's capers.
The video, which was captured by business owner Frank Duxbury, has been viewed nearly 10,000 times since it was posted on Facebook.
Mr Duxbury said: "He was such a brilliant dancer. He just kept dancing and dancing over again."
