Charlie Duncan

Charlotte "Charlie" Duncan is the second youngest of the Duncan family. She was originally the baby of the family, until it was announced in Good Luck Charlie It's Christmas! that her mother Amy was pregnant again with a new baby. She was born three weeks before she was due. Teddy, her older sister, is making a video diary for Charlie to help her with their "special" family and to give her some advice. She is currently 4 years old and in preschool. She spoke for the first time in Sleepless in Denver, but it seemed to have gone unnoticed by the family at that time. She is portrayed by Mia Talerico.
