Wasn't Seven a relative and not a child of the Bundys (something like Cousin Oliver)? I think they were going to bring in a separate child when Peggy was pregnant, but when she miscarried in real life, they made her pregnancy a dream (a la Bobby Ewing).

I also think Olivia and Jessie's twins from Full House were there because the younger children (Rudy and Michelle) had gotten too old to be cute. And that was the point when both shows jumped the shark.
