We've seen a number of mother-son dances from Zumba to traditional, but Amy Winn's dance at her son Stephen's wedding was special for a different reason. For almost two decades, Amy has battled multiple sclerosis, or MS, which has kept her in a wheelchair. In the emotional video above, she's lifted out of her chair and into Stephen's arms to share their first dance together. You can tell that it's such an incredible moment for the both of them. Stephen's wife, Cassie Winn, told the Today show that "there wasn't a dry eye in the house."
