Diane Sawyer participates in a December 2001 photo session with 17 babies born to widows of Sept. 11, 2001. That day the mothers were invited to meet and talk about their joys and pains. Sawyer and ABC News have followed the children over the years as they reached the Terrible Twos, as they entered kindergarten and, most recently, as they neared their tenth birthdays.
