Nicole Zistler and 10-year-old son Tristan talk about his adoption and birth father.
UPDATE: Tristan and his birth father met last November, and several times since. Nicole tells us "During their first meeting, Tristan and his birth dad kept staring at each other's faces, soaking in every feature. We were all nervous for the first meeting, but knew how much it meant to everyone. It's been a wonderful experience and I'm so glad we connected."
