Good Luck Charlie premiered on Disney Channel in April 2010, and began when Talerico was only 11 months old. It followed the Duncan family as they adjusted to having a new baby in the house. The family show went on to run for four total seasons, ending in 2014 after adding another baby named Toby to the mix.
Since then, Talerico has continued acting in television, including a role in the series Mani and a role in the series Conrad.
She also reunited via Zoom with her Good Luck Charlie co-stars to celebrate the ten-year anniversary of the show in 2020 for Entertainment Tonight.
“I probably had a really easy role ’cause I just got told most of my lines or didn’t have any. I think it was really easy because most of the time, it was what happened. We just rolled with it, like, in the crawling scene, I just stood up, so we just went with it,” Talerico said at the time.
As for a future reboot of the series, Talerico suggested, “I always felt like if we did do one, where I found Bridgit’s video diaries – that’s what I was always thinking, if that did happen.”
