Abby Newman is a fictional character from the American CBS soap opera, The Young and the Restless. The character was introduced on November 13, 2000, as the daughter of Ashley Abbott and Victor Newman . The role was portrayed by Darcy Rose Byrnes as a child until 2008, when the character was rapidly aged to a teenager, with Hayley Erin assuming the role the following year. In 2010, the character was rapidly aged again to an adult, with Emme Rylan cast as Erin's replacement. Rylan was let go in 2012 due to budgetary cuts, but returned months later in February 2013 on a recurring status following viewer complaints. However, her return was cut short once Rylan vacated the role to join General Hospital as Lulu Spencer. Melissa Ordway was then hired as her recast, who made her debut on April 16, 2013. Rylan compared Abby to her previous role, Lizzie Spaulding on Guiding Light, saying they were both wealthy heiresses who cause trouble. Upon Abby's return in 2013, Rylan felt that she had become "more mature".
