Good Luck Charlie is an American sitcom which originally aired on disney Channel from April 4, 2010 to February 16, 2014. The series' creators, Phil Baker and Drew Vaupen, wanted to create a program that would appeal to entire families, not just children. It focuses on the Duncan family of Denver as they adjust to the births of their fourth and fifth children, charlotte "Charlie" (Mia Talerico) and Toby (Logan Moreau). In each episode, Teddy Duncan (Bridgit Mendler) adds to a video diary that contains consejos for Charlie about their family and life as a teenager. Teddy tries to mostrar Charlie what she might go through when she is older for future reference. Each video diary ends with Teddy (or another family member, even Charlie) saying the eponymous phrase, "Good luck, Charlie".
