Good Luck Charlie

Good Luck Charlie is an American sitcom that originally aired on the Disney Channel from April 4, 2010, to February 16, 2014. Created to appeal to entire families, not just children, it focuses on the Duncan family of Denver, Colorado, as they adjust to the birth of their fourth child, Charlotte "Charlie" Duncan (Mia Talerico). In each episode, Charlie's oldest sister, Teddy Duncan, adds to a video diary that contains advice for Charlie about their family and life as a teenager. Each video diary ends with Teddy (or another family member) saying the eponymous phrase, "Good Luck, Charlie!"
