How many kids does Carla have by the end of Cheers?

The answer is: 8. At the start of Cheers, waitress Carla Tortelli is a mother to four children. She doubles her offspring by the end of the series. Along with her first four children, Carla’s fifth was fathered by Nick Tortelli (Carla put Nick through TV repair school, but he cheated on her and they divorced). The sixth child was fathered by Frasier Crane’s former mentor, the psychiatrist Dr. Bennett Ludlow. The youngest kids, twin boys, were fathered by the ice hockey player Eddie LeBec. Source
