With her sweet little smile, Sa’Diyah “Sadie” Pierce melts the hearts of those around her, and without saying a word, this 4-year-old charmer manages to get her point across. Sadie, the daughter of Samantha Smith and David Pierce, was diagnosed at age 1 with Turner Syndrome. A non-hereditary, chromosomal condition, the syndrome occurs in approximately 1 of every 2,500 female births and in as many as 10 percent of all miscarriages.
