Well “My Three Sons” actually featured four sons. The original sons were Mike (Tim Considine), Robbie (Don Grady), and “Chip” (Stanley Livingston). When Tim Considine left the show (after a fight with producer Don Fedderson over wanting to direct but not act in the series; this coincided with the departure of William Frawley and the series moving to CBS from ABC), the fourth son Ernie (Barry Livingston) was adopted by the Douglas family.
