Dear Sugar: What About The Stepchildren?

When the Sugars answered a letter from a woman who felt trapped in the role of "wicked stepmother," dozens of listeners wrote in asking the same question: what about the stepchildren, who have no control over the restructuring of their family? This week, the Sugars respond with an episode devoted to the other side of the story. They're joined by Jane Alison, author of the memoir "The Sisters Antipodes," which tells the story of how her parents swapped spouses with another couple when she was 4 years old.
