"That's the one," he said.

But for some families, there's heartbreak too.

In his series "Stories from the Big Chair," Caleb Ryan Sigmon is documenting his heartwarming encounters during his stint as Santa this year on his Facebook page. And one has gone viral. The post, from earlier this month, details an interaction he had with a man who came to his Santa station holding a photo of a baby.

The man told Sigmon his son had passed away last year. The post has been shared more than 55,000 times.
