Happy Birthday, Baby J! The Little People, Big World star is already seven months old, and he’s growing up so fast! On Tuesday, Dec. 12, Jackson’s proud mama, Tori Roloff, took to Instagram to share an update on her (seriously adorable) baby boy — whom she shares with her husband, Zach Roloff. Watch the video below to see his transformation!

“Jackson is rolling!” Tori wrote of his newest milestones. “He has two teeth and is working on a third! J is obsessed with his feet and will take off anything in his way of his toes.” She also added that he started eating “solid” food, loves to babble, and doesn’t like awkward silences. Same, J, same.

Earlier this week, Jackson met Santa for the first time, and he didn’t have much of a reaction! Tori posted the snap with the caption, “Okay I’m done. This kid kills me. We met Santa today and I think J would have taken a nap right there on his knee. His patience and curiosity just gets me. I hope you guys are enjoying this Christmas season as much as we are!”

Yet Baby J isn’t the only one celebrating a birthday recently. His bestie cousin, Ember Jean, just celebrated her three months with an update of her own. “Oh deer… 3 months already?!” mom Audrey Roloff wrote on Instagram. “This time last year you were growing inside of me and I didn’t even know it! Now your growing on the outside, getting chunkier and more kissable every minute. You may not remember your first Christmas, but we always will.” So sweet. Happy Birthday, you two!
