'Little People, Big World' Stars Tori and Zach Roloff Celebrate Son Josiah's Major Milestone in New Photos

Tori and Zach Roloff , former stars of Little People, Big World , might not be on reality TV anymore, but they make sure to keep fans up to date with everything happening with the family on social media.

In their newest update, the couple excitedly shared a major milestone for son Josiah , their youngest, as he transitioned from the crib to a "big boy bed."

The Roloffs posted photos of Josiah rocking a huge grin as he played around on his new bed in gray and white striped pajamas. He looked very excited about the new development.

"Our Si guy!! The last of our household to ditch the crib!!" Tori wrote in the caption. "Josiah is officially asleep in a big boy bed for the first time! My emotions are all over the place but the biggest feels I have right now is pride. I love our kids so much and tonight is emotional."

Going even further, Tori noted that putting away the crib was a "huge step," adding, "I will miss the infant/baby stage, but I’m also loving every moment of watching my kids grow and reach new milestones!!"

Tori also shared appreciation for her oldest child, son Jackson , for moving from the bottom to the top of the bunk bed so that Josiah could move in.

Zach wrote in the comments, "I can’t heart this post enough. Ps I was a top bunk kid so Jackson going to kill it up there!"

Fans were just as excited for Josiah's big news, with one fan writing, "This is a huge milestone for Josiah and I hope he rocked it!!! Also great job Jackson for moving to the top bunk!!!"

"He looks so excited!! Hopefully he sleeps through the night!!" wrote another, while a third person replied, "Oh my goodness that smile!! 😘."

Along with Josiah and Jackson, Zach and Tori also have a daughter named Lilah who is their middle child.
