Hvor er skuespillerne af mine tre sønner nu?
Mens de tre sønner altid har været centrale for handlingen, skete der flere store ændringer i slutningen af 1960'erne. I foråret 1967 begyndte seertallene for serien at falde, og My Three Sons sluttede sin syvende sæson på en 31. plads i Nielsen-seertallene. Det blev besluttet, at sæsonen 1967-1968 ikke blot skulle give programmet et nyt tidsrum, men også nye historier, der kunne pifte seertallene op. I efteråret 1967 flyttede CBS My Three Sons til lørdag aften kl. 20.30. I sæsonpremiereafsnittet "Moving Day" flytter familien Douglas og onkel Charley fra den fiktive by Bryant Park i Midtvesten til Los Angeles. Robbie (Don Grady) gifter sig med sin klassekammerat/kæreste, Katie Miller (Tina Cole). Tina Cole havde i øvrigt optrådt i forskellige roller i tre tidligere afsnit af "Mine tre sønner": "House For Sale" fra fjerde sæson (13. februar 1964), "The Coffee House Set" fra femte sæson (19. november 1964) og "Robbie and the Little Stranger" fra sjette sæson (17. februar 1966). Ved slutningen af sæsonen 1967-1968 var seertallene forbedret i forhold til året før, idet serien placerede sig på en 24. plads i Nielsens. I den følgende sæson opdager det nygifte par, at Katie er gravid, og hun føder trillinger ved navn Robert, Steven og Charles. Selv om de oprindeligt blev spillet af et sæt tvillinger, blev disse babyer spillet ukrediteret af Guy, Gunnar og Garth Swanson. De mest kendte trillinger i seriens sidste to sæsoner blev spillet af Michael, Daniel og Joseph Todd.
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. It was decided that the 1967-1968 season would bring the program not only a new time slot, but also new storylines to spice up the ratings. In the fall of 1967, CBS moved My Three Sons to Saturday night at 8:30 pm. 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. Robbie (Don Grady) marries his classmate/girlfriend, Katie Miller (Tina Cole). Tina Cole, in fact, had appeared in different roles on three previous episodes of My Three Sons: "House For Sale" from the fourth season (February 13, 1964), "The Coffee House Set" from the fifth season (November 19, 1964), and "Robbie and the Little Stranger" from the sixth season (February 17, 1966). 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. Although originally played by sets of uncredited twins, these babies were played uncredited by Guy, Gunnar, and Garth Swanson. The most familiar triplets in the show's last two seasons are played by Michael, Daniel, and Joseph Todd.
