TOUCHING: Couple weds with two-year-old dying son as best man [VIDEO]

Just two years old, the best man, Logan, is the son of the bride and groom, Christine Swidorsky and Sean Stevenson. The pair, who also have a one-year-old daughter together, wanted to share their special day with Logan, who is sick with a rare genetic disease and has been given just weeks to live.

“This is our dream come true. All our family together and we’re all together celebrating, the celebration of my son’s life and the celebration of our marriage,” Swidorsky told WPXI Saturday.

Swidorsky and Stevenson had already been planning their wedding, but moved up the big day once they knew their son’s life was nearing its end. “We'd been planning a wedding — we were starting to look for halls, but we decided to have it now so Logan could be a part of it, so he could be in the pictures — so it could be something our family did together," the couple told today.com.
