Career
Becoming a child actress at the age of ten, Haddock is perhaps best known for her role as tomboy "Cindy Webster" on the National Broadcasting Company television series The Facts of Haddock"s character was quietly written out of The Facts of Life after the first season. The producers explained they wanted to take the series in a new direction, and because National Broadcasting Company had few assets, they fired more than half the original cast. Although no longer a series regular, Haddock continued to make a limited number of guest appearances on the show during seasons two and three, for the sake of continuity.
Her final appearance on the show was in the season eight episode "The Little Chill" (1986) which was also her last listed acting role.
She is also known for her appearance on the Wonder Woman television series as the super powered girl, Amadonna, in the episode The Girl from Islandia and as Robert Duvall"s daughter in the movie The Great Santini. She also appeared as Melinda Mulligan, the daughter of Lawrence Pressman and Elinor Donahue on the short-lived National Broadcasting Company series, Mulligan"s Stew, in 1977.
In the 1983-1984 season, she appeared on National Broadcasting Company"s short-lived Boone starring Tom Byrd and Barry Corbin. Since then Haddock has retired from the public eye.
She was briefly interviewed for the Digital Video Disc release of The Facts of Life and explains that she also gives her time to fundraising.
In 2008, Haddock, along with Molly Ringwald, Felice Schachter, and Julie Piekarski, was nominated for a television Land Award, in the category Favorite Characters Who "Went Missing".
