Jealous! The youngest stars of OutDaughtered — aka the cute quints and their big sis Blayke! — attended a unicorn-themed birthday bash late last week, and apparently, our invite got lost in the mail? Adam Busby took to Instagram to share a sweet snap of the girls helping their dad move the inflatable balloon, and it’s the sweetest. 

“The quints helping me unload a giant unicorn last night out of my truck for McKenzie’s birthday party,” the father-of-six wrote on Aug. 11. “I got some funny looks driving down the road with this thing in the bed… #happybirthdaymckenzie #outdaughtered.” Hmm, we hope that last hashtag means it was filmed for the show!

McKenzie is the daughter of Dale Mills (aka Uncle Dale) and Crystal Mills (aka Aunt Kiki). The two have become fan favorites on the hit TLC show, particularly Dale — who loves playing pranks on the kiddos! That said, he also has a sensitive side.

During Season 2, Adam underwent his first session with his therapist for postpartum depression, and for a while, he hadn’t told Dale or his other brother-in-law, Nick, about his struggles. “Dale, for one thing. I mean how the heck is he going to react to something like that? He’s just going to make jokes,” Adam said. Luckily, he took the news rather well. “It’s hard for me to be serious sometimes, but this isn’t something I would joke about. Ever,” Dale said. “I’m glad we got to talk.” 

Dale and Crystal — who is Danielle’s sister — took to Instagram as well to wish their little girl a Happy Birthday. “Top off the day with a Unicorn birthday cake for the birthday girl!” Dale wrote on a pic of the fam. “#weloveyoukenziegirl #gotmyhatbackfromhazel #mowbraysbusbysandmimioverforcake.” Crystal, meanwhile, revealed slime making went down at the shindig. “Who’s ready to make SLIME?!?” she asked. “These girls are!!”

Back in April, Blayke celebrated her big day by teaming up with the educational toy company, Learning Resources. At the time, her proud mom sat down with In Touch and gushed about her first-born. 

“Blayke is something special, for sure,” she said. “She always has a heart for others, especially kids that are more in need. She just has that heart where she’s always wanting to help someone else — whether it’s seeing kids in her own classroom, or her sisters, or families in need, and even doing other projects like giving back to our community since Hurricane Harvey.” She continued, “When we were going to do this playdate birthday party for her, she came up with the idea to invite some kids like we did last time. I was like, ‘Of course we can!'” So sweet!
