The world’s oldest mother died last week. She was a Spanish woman who gave birth to twins when she was 67. But cancer took her life just three years after giving birth. This week’s family segment will explore the issue of starting a family later in life. Joining The Takeaway is Lisa Belkin, who wrote about the issue in The New York Times blog Motherlode: Adventures in Parenting. Also joining us is journalist Karen Day, a 56-year-old mother of a three-year-old, who also has three other children.
