Tori and Zach Roloff’s son is growing up right before our eyes. The “Little People, Big World” stars shared an update on Instagram regarding their baby boy on Tuesday.

Tori and her husband shared the same photo of Jackson lying on a sheet surrounded by numbers representing his age. Tori also shared a few fun facts about the 1-month-old, including that he’s been enjoying soccer matches with Zach, is getting increasingly vocal and has developed a fondness for uncle Jacob Roloff. The “Little People, Big World” stars’ son, however, isn’t a fan of diaper changes or bath time, according to his mother and father’s Instagram post.

Days before he turned one month old, Zach shared a close up of Jackson. The photo shows the newborn lying down with his tongue sticking out. In the caption, the “Little People, Big World” star joked that Jackson enjoys “peeing when dad and mom are changing my diaper,” among other things.

These are the first photos Tori and Zach have shared since revealing that their son was diagnosed with Achondroplasia. Although they haven’t posted many photos, they’ve been open with the public about his stature and the struggles he may face. In a People magazine interview, Tori and Zach revealed their hopes and dreams for his future, stating that above all they hope he’ll grow up “to be a good person.”

“Whatever he wants to do in life, we’re going to find a way to help him do it. That’s our job in life now,” he said.

The couple confirmed Jackson’s dwarfism in a separate interview with the publication. Tori and Zach vowed to parent him just as they would an average sized child. Zach said that Jackson may require “a little more” encouragement, but won’t be getting cut any slack from him.

“You have to encourage a dwarf child a little more because it will take them six steps to do what others can do in two,” the “Little People, Big World” star said. “But I knew, dwarf or not, I was going to parent my child the mentality that not everyone gets a trophy. You have to earn it.”

Zach and Tori made the decision to share his diagnosis in the hopes that it would help others in the same situation. Zach told the publication that his son will face a lot of struggles as he learns and grows, but said there’s so much more to him than his diagnosis. The new father added that there has been an overwhelming response to his and Tori’s openness.

“Tons of parents email me to say what an inspiration we are for their kids, showing that it’s possible for them to get married and have a family,” he said. “The other day we met a couple who have a dwarf child. They started watching our show and it made them feel that it was all going to be okay.”

Prior to his birth, Zach and Tori opened up about the possibility of Jackson being a dwarf on “Little People, Big World.” Speaking with his mother Amy Roloff, the expectant father said that the baby was “measuring below average.” He expressed a fear that his son would face bullying as he grew up, which he wanted to avoid.

“What am I going to say? ‘Oh yeah, I want a dwarf baby? I can’t wait for that kid to be bullied,’” he said on the TLC series, according to People.
