Darlene tells David in the episode Another Mouth to Shut Up that they got pregnant at Disney World after the fireworks. The episode, Disney World War II originally aired February 27th, 1996. This episode aired February 25, 1997. Darlene has technically been pregnant for almost a year. Additionally it's said, the baby was born about 2 months early, which would have been 7 months.
At the end of the episode, we are shown shots of Harris recovering and living with a version of the song Blackbird by the Beatles playing in the background. The song is not on the DVD.
Darlene says that she's never smoked or drank, and only used drugs once. But she first smoked in "Bridge Over Troubled Sonny", and then she picked up smoking again when she was living with Jimmy. Also, when it was revealed Darlene had tried drugs, she had done it more than once since she admitted to using acid twice as an example.
Becky: I really have a bad feeling about this.
Bev: Don't talk that way Becky. As Louise Hays says, you must learn to turn the negative into a positive.
Roseanne: Yeah, you should listen to your Grandma Becky. Apparently being gay means more than wanting to wear flannel shirts and Birkenstocks. It also makes you smarter.
Jackie: (to the baby) I remember when I was about 5 and we were riding in the car, and I was leaning up against the door, and suddenly the door just flew open, and I was falling out of the car...I remember because I could see the road rushing right below me, so I was literally outside of the car...and out of nowhere, Mom reached over and pulled me back in by my hair...and, if you ever feeling like you're falling away, you don't have to worry because we'll be right there to pull you right back in.
Bev: (to the baby) Oh, you've got quite a grip...I think you're a lot stronger than you're letting on.
Jackie: There's 12 doctors on the list and we've called ten.
Roseanne: Well maybe, then it's time we tried an alternative.
Jackie: What, like...acupuncture?
Roseanne: Well yeah, or an herbalist or a natural healer...western medicine don't know everything, and there are countries where they do that stuff...like I read that in India, they take sick people down and bathe them in holy water.
Jackie: No, you're making that up, that stuff doesn't work.
Roseanne: Yes it does work, Jackie, I read it in all of Nancy's books and they all said the same thing, it works because they believe it's going to work.
(2 nurses watching all the Conner women huddled around the new baby)
Nurse 1: What's going on?
Nurse 2: I'm not sure, it looks like some sort of coven.
Darlene: If there's nothing physically wrong with me and I didn't do anything morally wrong, then nothing makes sense. What did I do to deserve this? Why was my baby born prematurely?
David: You didn't do anything to deserve this, you don't deserve this...our baby doesn't deserve it. It just happens.
Darlene: I don't know why this is happening. I never smoke or drank and I only did drugs once.
David: And that was a long time ago.
Darlene: Maybe I ate the wrong stuff...
David: You're a vegetarian, you're the healthiest eater I know.
Darlene: Well if it's nothing physical, then I must have done something wrong and now I'm being punished.
Roseanne: The doctors are still examining her.
Mark: How long does it take to examine a baby? She's only this size...sorry.
Roseanne: We are not bodies with souls. We are souls with bodies.
(Darlene is about to have her baby)
David: So, is there anything we wanted to do before becoming parents?
Darlene: Well, we were going to go to Paris.
David: (smiles) I think we're gonna be late for the flight.
Darlene: (chuckles) I'll settle for a cheese omlette then.

In the ending credits while Darlene's premature baby is shown, the doctor from Australia says "Amazing...I've never seen anything like this," proving that the baby lives.
