For our 25th Anniversary, a favorite episode from 2008. On a summer day in 1951, two baby girls were born in a hospital in small-town Wisconsin. The infants were accidentally switched, and went home with the wrong families. One of the mothers realized the mistake but chose to keep quiet. Until the day, more than 40 years later, when she decided to tell both daughters what happened. How the truth changed two families' lives—and how it didn't.
