Roloff shares his three kids — Jackson, Lilah and Josiah — with wife Tori

Zach Roloff’s son is getting ready to take his first steps.

During Tuesday’s episode of Little People, Big World, the dad of three, 33, reveals that his younger son Josiah, 22 months, is starting to take his first steps. While his wife Tori is away on a girls’ trip, Zach helps Josiah work on putting one foot in front of the other.

“Guys want to practice some walking?” Zach asks as he lifts Josiah from the ground. “Hey hey hey!”

Josiah places his hands on a toy walker while Zach monitors him. “Okay, we’re going to walk all the way to the living room,” Zach says as Josiah places one foot in front of the other.

Zach shares his three kids — Jackson, 6, Lilah, 4, and Josiah — with Tori.

“The kids and I have gotten into a nice little routine throughout the day,” the proud father says in a confessional. “After lunch, the three of us will hang out for a while and then it’ll be time for us to pick Jackson up from school.”

The scene switches back to the family’s house, where Josiah keeps walking, babbling and giggling as he goes.

“Si’s doing great walking. He can’t catch himself if he falls. Once we’re up though, he’s doing pretty good with walking,” Zach can be heard saying.

“Yay Si-si!” sister Lilah says as she watches her brother take a few steps, clapping her hands.

“Good job Si-Si, let’s take a little break,” Zach says as he lifts his son gently to the floor, moving the toy walker.

In May, the Roloffs celebrated Josiah’s first birthday with a “Josiah’s first rodeo”-themed celebration.

In photos Tori shared on Instagram, Josiah posed in his high chair, adorned in a cowboy-themed garland, smiling under a sign that said “Josiah’s 1st Rodeo,” and a balloon arch of brown, tan and cow-print balloons.

“I still can’t believe my last baby is 1! I just love him so much and want to keep celebrating the day!!” she captioned the set of shots.
