James O'Leary weighed barely over a pound when he was born by surprise in New York, a world away from his home in Australia.

His mother was nearly six months pregnant when she went into labor while on vacation. It became an anxious four-month sojourn, with James in intensive care at Bellevue Hospital.

Nearly six years later, he went to Bellevue Wednesday for a reunion with the doctors, nurses and other staffers who cared for him. They became a surrogate family when the O'Learys were far from their own.

Neonatologist Dr. Pradeep Mally says James couldn't breathe on his own when born, but he "was a fighter."

Now, he's a healthy, typical kindergartener. He lives in Sydney with parents Brett and Jennifer O'Leary and three younger siblings.
