Jessa and Ben Seewald's wedding may have been the focus of Tuesday night's episode of "19 Kids & Counting," but the couple was already discussing the possibility of adding to their family.

While enjoying a painting session with family members Jill and Derick Dillard, Jessa imagined what it would be like to be expecting.

"I'm really excited to have a future niece or nephew I'll get to spoil," Jessa said in a confessional. "It just makes me stop and think, man, that could be Ben and I real soon."

Jill and Derick are expecting their first child, a boy, on March 24. The couple became pregnant less than two weeks after their wedding day, leading Jessa to consider the possibility that she and Ben could become a three relatively quickly.

"I guess I'm ready for it," she revealed in Tuesday's episode. "I mean, I don't think I'd be getting married if I didn't think I was ready to start a family."

Jessa, 22, and Ben, 19, were married on November 1, and there has not been a pregnancy announcement yet. The couple has shared that they plan to adopt children, whether or not they are blessed with biological kids.

"Kids are so important," Ben told PEOPLE Magazine in an interview published earlier this month. "We hope to adopt a lot of kids. If God blesses us with biological children of our own, it's not going to quench our desire to adopt."

"Even before we married, we wanted to adopt," Jessa added.

Soon afterwards, the Duggar family clarified on their blog that the young couple's plans were temporarily on hold.

"The Seewalds researched adoption but discovered that most agencies require a couple to be married for two years before adopting," the blog read. "Still, they hope to adopt 'a lot of kids,' as Jessa puts it."
