They grow up so fast! Little People, Big World star Tori Roloff took to Instagram to share an update on her son Jackson’s five-month birthday, and seriously, where does the time go?! Her sweet baby boy — who she shares with husband Zach Roloff — has already grown up so much. In fact, he’s even sleeping in his own room now! Watch the video below to learn more about his other milestones!

Over the weekend, Baby J got to enjoy his first weekend at the Roloff Farm pumpkin patch. The best part? He got to celebrate the exciting moment alongside his newborn cousin, Ember, Audrey and Jeremy Roloff’s first child. Tori’s pumpkin patch post came just days after she shared a touching Instagram photo of her son cuddled next to Ember and holding her hand. “No worries cousin Ember… Baby J will always be there to hold your hand. ❤️ we love you little girl!” the mom-of-one captioned the pic. “#babyjroloff #roloffcousins”

Recently, Auj — who gave birth to Ember on Sunday, Sept. 10 — updated fans about her baby girl’s looks. “We think she looks like Jeremy so far, but she might have a little glimmer of strawberry in that peach fuzz hair. Only time will tell!” the curly-haired redhead wrote on her personal blog. “We are still hoping for boing boing curls though.”

Last month, Audrey and Jeremy got super candid about her delivery during an interview with Us Weekly. “Labor is such a wild and miraculous process and meeting our baby girl for the first time filled us with uncontainable joy,” the couple, who tied the knot in 2014, said. “We are so thankful for this little life we’ve been blessed with and cannot wait to see all that she becomes.”
