Earlier this year, Kourtney and Scott Disick—who also share daughter Penelope, 10—celebrated another of Mason’s milestones: finishing the sixth grade.
Kourtney celebrated her son’s accomplishment with a congratulatory Instagram Stories post that included a balloon display that spelled out, “Yay Mason passed the 6th grade.”
“Congrats Mason you passed the 6th grade,” Scott wrote alongside the photo on June 1, “let’s party.”
As for Reign, well, Kourtney recently admitted she’s still holding on to her little one in a unique way: with a lock of hair.
“I have Reign’s hair, because we didn’t cut his hair until he was five,” Kourtney said in an Interview Magazine piece in November. “So I have his long braid and I smell it often.”
