One of the most well-known examples of a "Daughter Swap" program is the MTV reality show "Daughter Swap," which aired in 2009. The show featured two families, the Millers and the Williams, who swapped their 15-year-old daughters, Miranda Miller and Jourdan Miller, for a month. The show aimed to explore the challenges and benefits of swapping families, as the daughters adapted to new environments and the families learned to adjust to having a new member.
