Little People, Big World stars Tori and Zach Roloff have a 2-year-old on their hands!

On Tuesday, Tori took to Instagram to celebrate her and Zach’s baby boy.

“Happy birthday to our sweet Josiah Luke. You are the most entertaining, silly, stubborn, sweet, loveable dude. The lord knew we needed you. He knew how much joy you’d bring to our lives every single day. You are ready to adventure and just need those little legs to catch up to everyone!!,” she wrote. “You are the definition of a daddy’s boy and can’t see anyone else in the room when @zroloff07 is next to you. You put up with a lot of wrestling and hair styling from your siblings and let mom get cuddles in when they’re needed!”

Tori’s post was accompanied by a series of portraits of Josiah, who has curly blonde hair, as he smirks for the camera, and shows off his piercing blue eyes.

Before wrapping her sweet birthday tribute to her youngest son, Tori shared her guilt for not being able to give him the usual celebrations — as she and Zach both fell ill.

“This birthday doesn’t look the way I thought it would this year. Mom and dad are sick,” she wrote. “Mom threw out her back. And the house is torn apart to finish repairing the broken pipe we had. But Si guy we love you so much bigger than today and we will celebrate properly ASAP. I love you Josiah! Happy birthday! 💙✌🏼.”

Prior to her post on her grid, Tori took her Instagram followers down memory lane on Monday. Taking to her Instagram Story, the Raising Heights host shared pictures from Josiah’s first moments home from the hospital, his first birthday celebration, matching moments with his father and siblings, and more recent shots showing how much he has grown in the last year.

“One more sleep as a one year old,” she penned on the final photo. “We love you sweet boy.”

Tori and Zach are also parents of Jackson, 6, and Lilah, 4.

Josiah’s birthday comes amid big changes for Tori and Zach. Following the end of the recent season of Little People, Big World, the duo decided to depart the series — which Zach has been a part of since 2006 — amid family tension.

“We are not [coming back], and we made that pretty clear the last cycle,” Zach said in February when they officially made the announcement. “This last cycle was rough between the family, the farm deal and we’re done with that. We’ve moved on.”

He added, “I think the chapter has closed regardless of us being asked back or not. We’ve made it pretty clear we’re done with that chapter for multiple reasons, the reasons we will get into here.”

Prior to his departure, Zach’s twin brother, Jeremy, 33, and their younger siblings, Molly, 30, and Jacob, 27, all departed in prior years.

On Monday, Matt Roloff spoke candidly about the future of Little People, Big World, after he claims a 20-year NDA expired.

“I do think that TLC did a nice job on the last Tuesday ‘season finale’ episode hedging their bets and putting a nice button on the show and where the family (members that still participate) stands,” he wrote. “So if LPBW never does come back (in whatever various other forms) I think consensus is they wrapped up the Roloff LPBW crazy train saga pretty good–  That’s why many of you felt it was a series finale.”
