He’s 2 months old already!!

On Wednesday, the newest addition to the “Little People, Big World” family hit his two month birthday and mom Tori Roloff has no idea where the time is going!

Our Baby J is two months old today! How?!” she wrote alongside his photo. Roloff also listed a few milestones little Jackson has hit since making his debut in May. “Baby j is sleeping a consistent 7 hours! πŸ’€ Loves smiling at mom and dad! πŸ™‚ Falls asleep during pool time 🏊  Gets excited when we change his diaperπŸ™ŒπŸΌ LOVES bath time. πŸ› Hates being hungry. 🍼 Jackson is 98th percentile for height and weighs over 12 pounds!πŸ‘ŒπŸΌ Keep growin baby J! πŸ’™ #zandtpartyofthree.”

After his birth, the couple announced that their son was born with achondroplasia, like his father, Zach Roloff. Achondroplasia is the most common form of dwarfism, and the couple knew they had a 50/50 chance of passing the gene on to their child.

β€œWe knew our chances of having a dwarf, but it didn’t matter,” Tori said to PEOPLE at the time. β€œWe just knew we wanted to be parents, however God wanted it to happen.”

By the looks of this latest update, this little gift is growing up fast!
