I think a lot of people who were or had kids pre-internet streaming probably watched PBS, at least sometimes.
Sesame Street, Mr. Rogers, Reading Rainbow, Joy of Painting, Arthur, Bill Nye, Barney, Teletubbies, etc.
It's not like there were a lot of TV choices for kids if their parents couldn't afford cable (and some stations like Cartoon Network didn't even exist until 1992+, I think even Disney Channel was a premium channel like HBO).
