It's an especially little person for the stars of Little People, Big World.
On Friday, May 12 Zach and Tori Roloff welcomed their first child together, a son they’ve decided to name Jackson Kyle Roloff.
"Mom and Dad are so in love with you already," Tori captioned this photo.
The newborn weighed in at nine pounds and one ounce and measured 20.5 inches long at the time of his birth.
“Baby and mother are doing great and Jackson is already mastered holding daddy’s fingers and snuggling with mom! He is adorable and Tori and I are loving being parents,” Zach said in a statement.
The reality stars were also generous enough to share the above family photo on Instagram, along with the precious mother-son snapshot below.
The couple got married in July of 2015 and announced in November that they were expecting a child.
That same month, the proud father-to-be revealed how Tori told him about the pregnancy.
"I walked into the house and she had written it on a notepad that she was practicing her calligraphy, so I was reading through this," he remembered in a TLC video, adding:
"On the last page, she wrote, 'You’re going to be a dad!’ and I skipped right over it. Then she said, 'Wait, hey, you missed it!' Then she pulled it back and I read it."
From there, the stars hosted a gender reveal party where they found out in front of 50 of their friends and family members that a son was on the way.
“We are super excited and can’t wait to be parents,” the couple said at the time.
On a subsequent episode of their series, however, both Zach and Tori expressed some anxiousness about becoming parents.
“I do not feel prepared one iota,” Tori said at one point on the TLC program.
This is the first grandchild for Zach's parents, Matt and Amy Roloff.
However, Zach and Tori aren’t the only members of this family who have a bun in the oven - Zach's twin brother, Jeremy and sister-in-law Audrey are also expecting a baby girl.
