On Little People, Big World, Zach Roloff has admitted his fears of future paralysis.
But he and Tori have other, happier plans for the future that they aim to set in motion: more children.
They already have little Jackson, and they want to give him a small army of younger siblings.
Zach and Tori Roloff sat down with Us Weekly to discuss their wonderful family -- and how they intend to make that family grow.
"We have plans," Zach promises.
He then makes it clear: "We want a family."
Obviously, they have a family. He and Tori were a family even before they had baby jacskon in 2017.
But Zach has a larger brood in mind.
"I would love four or five kids," he reveals, adding: "I want a little pack."
That said, they're not going out of their way to try to guarantee offspring in the immediate future.
"Right now," Zach explains. "Weâ€™re just kind of [like], if it happens, it happens."
Reading between the lines, it sounds like they're banging, but not doing any sort of fertility treatments to increase their chances.
Tori chimes in, talking about leaving things to chance for the moment.
"Itâ€™s just on Godâ€™s timing and just whenever," Tori says. "Weâ€™re ready for it."
The couple also opens up about their son, Jackson, who is just about two years old.
(His second birthday will be May 12, 2019!)
Zach shares that little Jackson has been "running a lot more" these days.
"Heâ€™s talking more, heâ€™s mimicking more [and] he can understand more. â€¦" Zach elaborates.
He summarizes: "Heâ€™s just doing everything a little bit better lately."
Jackson enjoys being on Little People, Big World.
"He really likes the crew, which is nice,â€� Tori comments.
Some toddlers love seeing familiar faces and meeting people and being filmed. Jackson is clearly one of them.
â€œHe loves watching the cameras," she shares. "And watching them all move."
"For him," she adds. "Itâ€™s still fun."
That last comment is a great reminder that, for adults, being a reality star can be exhausting over time.
The couple also discusses Jackson's cousin, precious baby Ember Jean.
"Ember comes over and stays at our house," Zach reveals, saying that this happens when "Jeremy and Audrey are doing their own thing.â€�
Like recently, when they've been on tour pushing their book about marriage now that they've been married for all of four and a half years.Â
However, he says that the little cousins are very different people.
â€œ[Jackson] doesnâ€™t like being touched and manipulated, I guess," Zach explains.
In contrast: "where Emberâ€™s very, like, let me give you a hug and a kiss and let me love on you."
Ember is a cutie-pie and you can hear Ember talking in this video.
"They get along well," Zach clarifies. "Donâ€™t get me wrong,"
"But," Zach explains. "Jackson definitely has his moments where heâ€™s like, â€˜Okay, just give me space.'"
That is extremely reasonable and normal.
Even toddlers are their own people with their own personalities.
It doesn't mean that they love each other any less.
