By Daily Mail Reporter PUBLISHED: 17:51 EST, 13 November 2013 | UPDATED: 06:23 EST, 14 November 2013 It was the shocking discovery that tore two families apart and forever changed the security procedures of U.S. hospitals. Now, 18 years later, America's most widely-reported case of two children who were switched at birth continues to remain relevant - and one of the girls has given a rare interview about how it has affected her as an adult. Callie Johnson was just three-years-old when single mother Paula Johnson discovered the toddler was not biologically hers. Her biological parents were Kevin Chittum and Whitney Rogers, and the daughter they took home and raised, Rebecca, was actually Paula's birth child.
