The baby girl Jim and Pam have together in season 6 of “The Office” is Cecelia Marie Halpert. Her parents usually call her CeCe.
Cecelia is Jim and Pam’s first child. Pam’s pregnancy is implied at the end of season 5 after she injures her ankle during the company picnic, then confirmed in the season 6 premiere. Jim and Pam marry in “Niagara,” and their daughter is born later in the season in the two-part episode “The Delivery.”
The episode follows the couple through a chaotic hospital visit, including Pam’s difficulty with labor and Jim’s accidental injury while trying to help her. The baby’s birth becomes one of the season’s major storylines because it changes the couple’s routines and affects their relationships with coworkers and family.
Viewers sometimes answer simply “CeCe,” which is the character’s familiar nickname. The full name, however, is Cecelia Marie Halpert. She is later joined by a younger brother, Phillip, whose birth becomes part of season 8.
