In the first season, Kim becomes pregnant with her second child; she and Bob also have a daughter named Serena. In order to help to provide for their growing family, and to keep herself occupied, she takes a job at a local radio station known as KTML "The Missile". Between the 1st and 2nd seasons of the show their son, Theodore "Teddy" Roosevelt Brown, is born. Her closest friend in the group is Tiffy Gerhardt, although Kim sometimes will distance herself from Tiffy due to the bad decisions that Tiffy continually seems to make.
