Christine Swidorsky and Sean Stevenson were supposed to get married in July of next year, but they moved the date up to tomorrow instead for one important reason: so their 2-year-old son, Logan, can serve as best man, reports the Pittsburgh Tribune-Review. Doctors have given the toddler, who has battled leukemia and a host of other diseases most of his life, two to three weeks to live. They sent him home last week, prompting this weekend's backyard wedding. “We want Logan in our family pictures, and we want him to see his mother and dad get married,” says mom. “It hurts so bad because Logan is such a loving child," she adds. "When I cry he wipes my tears away."
