Their little boy is growing up so fast! Little People, Big World stars Tori and Zach Roloff welcomed their first child, baby Jackson Kyle, in May 2017… and it’s been a nonstop adventure ever since. Luckily for us fans, the proud parents have been documenting all of Jackson’s firsts on Instagram. From his first time at the zoo, to his first Halloween, to his first flight, we've seen it all, and boy, is Jackson growing up fast! These candids show not just his progress, but also Zach and Tori’s devotion to one another as they embark on this new chapter of life.

“There’s not a single person I’d rather [be] taking this journey of parenthood with,” Tori wrote about Zach last year. “Seeing you with Baby J makes me fall more and more in love with you.”

And Tori couldn't help but gush about Jackson back in May for his big first birthday! "This year has brought nothing but joy to our family and it’s all because of this guy right here. Jackson’s personality has really taken shape this month. And by golly he is hilarious," she wrote on Instagram. "He is pulling himself up on anything he can reach and is so close to taking his first steps. He loves his dad so much and yells at him from across the room if he isn’t paying attention. Baby J weighs 21 pounds and has 8 teeth! I love you so much, bud. This year has gone by way too fast. You bring me such happiness and you have spoiled me as your mom." We can't wait to continue to follow their adventures, but for now, check out adorable photos of Jackson Roloff below.
