The gay couple who adopted the baby boy they found abandoned in the subway say he's thriving.

Twelve years after Danny and Peter found an abandoned day-old infant in the New York City subway, the men were married with their son, Kevin, by their side.

In a The New York Times op-ed titled We Found Our son in the Subway, Peter recounted the day he got a frantic call from his partner of 3 years.

“I found a baby!” Danny shouted from the subway. “I called 911, but I don't think they believed me. No one's coming. I don't want to leave the baby alone. Get down here and flag down a police car or something.”

At a family court hearing, the judge asked, “Would you be interested in adopting this baby?”

“Yes,” Danny answered. “But I know it's not that easy.”

“Well,” the judge responded, “it can be.”

At Kevin's suggestion, the men were married last July by the same judge.

“We weren't supposed to be there, two men, with a son we had never dreamed of by our side, getting married by a woman who changed and enriched our lives more than she would ever know,” Peter wrote. “But there we were, thanks to a fateful discovery and a judicious hunch.”

Appearing Friday on Anderson Cooper Live! the couple said Kevin is thriving. (The video is embedded on this page. Visit our video library for more videos.)
