Whirlwind wedding allows dying tot to be best man for his parents

(CNN) -- Dressed in a tan suit and an orange shirt matching his mom's bouquet, 2-year-old Logan looked on as his parents exchanged vows and rings at a backyard wedding.

Guests who gathered under a white arbor in the Jeanette, Pennsylvania, home applauded -- but many with tears in their eyes.

Because this union of Christine Swidorsky and Sean Stevenson was no ordinary wedding.

The couple had planned it for ages, and had penciled July 2014 as their special day. But that was before they learned that their best man -- Logan -- had just weeks to live.

The boy is suffering from leukemia, brought on by a genetic disorder, Fanconi anemia.

"We've been waiting for this day for a long time, but under the circumstances with Logan being sick all the time, we just held off," Stevenson told CNN affiliate KDKA. "We always knew he was going to get better."

"But under the circumstances of what the doctors told us, we just decided to go ahead and do it while he was still with us."
Christine Swidorsky carried Logan down the aisle. His grandmother cradled her in his arms, his favorite brown teddy bear by his side.
"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 said, as Etta James' "At Last" played in the background.
