(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."
