It’s all about Baby Roloff on this week’s Little People, Big World.

In an exclusive sneak peek at Tuesday’s episode, Zach and Tori Roloff take a moment to look over their most recent ultrasound as they prepare to welcome their baby boy.

“Today we had our third ultrasound, and we’re really starting to see what Baby Roloff looks like,” says Zach, 27. “It’s making things really real for us. I can’t wait to meet him.”

“He’s picking his little nose!” he adds, pointing to the ultrasound with a laugh.

“He’s just a nose picker — just like his daddy!” jokes Tori.

But adorable ultrasound aside, there’s something else Tori wants to talk to her hubby about: whether he plans on cutting the umbilical cord.

“No!” says Zach with a grimace. “No, no, no.”

“Yes, you are!” insists Tori. “That’s your job.”

“A trained physician doesn’t do that?” asks Zach.

Says Tori, “I’m going to get my blood drawn, I’m going to push a baby out of my hoo-ha, I’m going to get an IV put into my hand, I’m going to get an epidural stuck into my back — you can cut the baby’s cord.”

In another scene, we see why Zach might be a bit squeamish about cutting the cord. In a sit-down, Zach’s father, Matt, admits it wasn’t common for dads to cut their children’s umbilical cord back when he was having children.

Says Matt, “You don’t know what’s going to happen — is it going to squirt? Is it going to squish? You know, that kind of stuff can gross you out if you’re not focused.”

Of course, all’s well that ends well: PEOPLE confirmed on Sunday that the couple welcomed their baby boy, son Jackson Kyle Roloff, who weighed in at 9 lbs., 1 oz., and stretched 20.5 in. long.

“Baby and mother are doing great and Jackson is already mastered holding Daddy’s fingers and snuggling with mom!” said Zach. “He is adorable and Tori and I are loving being parents.”
