Since entering the world on May 12, Jackson Roloff has stolen the hearts of Little People, Big World fans. The littlest member of the Roloff family has grown so much over the last few weeks alone, and proud dad Zach‘s most recent photo shows Baby J morphing into his mini me! The 27-year-old chose to go captionless and instead used the hashtags “#gameday #gameface #portlandtimbers #outfitprobablywontlasttillgametime” and “#blowouts.” Adorbs!

Earlier this month, a photo of Jackson sparked rumors that he was a “rainbow baby” — a term used for a child born after a miscarriage. Despite there being a rainbow on his forehead, fans were convinced that the new parents’ son is a true miracle. “Did she have a miscarriage prior to Jackson? If not, this is a sh-tty way to use the term ‘Rainbow Baby.'” Another added, “This I did not know…” Note: He’s NOT a rainbow baby!

As Tori and Zach previously revealed, Jackson has achondroplasia, which is the same form of dwarfism his father has. In a recent episode of their vlog, Z and T Party of Three, Zach said, “Baby Jackson came in as [a little person] — just like me. Yeah, we’re super excited for it, though. We’ll hope to just give him a healthy, happy life and support him in every way. He can experience as much of the world as Tori and me[sic] have been able to and hopefully much more!”

He’s only just celebrated his three-month birthday, but the new parents already seem to be doing a great job! Although it hasn’t been without a few bumps in the road — Tori admitted she’s been having difficulty breastfeeding — the little guy is making progress. Just recently, Jackson experienced a growth spurt and Tori took to Instagram stories to post a photo with the text, “I think we’re going through a growth spurt” and used a crying emoji. Like his mama, we’re sad too. Slow down, Baby J!
