New input: While the three sons were always central to the storyline , several major changes took place by the late 1960s . In the spring of 1967 , the ratings for the series began to sag and My Three Sons finished its seventh season in 31st place in the Nielsen ratings .

In the season - premiere episode , '' Moving Day '' , the Douglas family and Uncle Charley relocate from the fictional town of Bryant Park in the Midwest to Los Angeles .

At the end of the 1967 - 1968 season , the ratings had improved from the previous year with the series placing at 24th in the Nielsens . The following season , the newlyweds discover that Katie is pregnant , and she gives birth to triplets named Robert , Steven , and Charles .
