Kailyn Lowry‘s unbelievably precious son Lincoln is officially a member of the single digits club, folks. That’s right, the “Teen Mom 2” tot is ONE!
Naturally, his doting parents couldn’t help but give the birthday boy some extra-special love this past weekend.

“My littlest little turns one today!” the proud mama captioned the collage-style Instagram snapshot of her nugget with his loved ones, above, on Sunday (November 16). “I cannot believe it’s been one whole year! I’ll keep the sappy stuff for his first birthday card! love him too much for words.” You can share the mushy sentiments, Kail. We’re ALL ears.

Meanwhile, Lincoln’s adoring dad Javi wrote his mini-me a very sweet Instagram note with a photo of the duo, above. “A big happy birthday to 1/3 of my world!” the airman and new college student added along with the father-son bonding moment. “Don’t need to say much else cause I’ll tell you as we all grow together. I love you Lincoln Marshall.” Can somebody pass the Kleenex, please?
So how did the tyke celebrate? With a barnyard-themed bash — complete with ponies, cowboy hats, tasty treats and plenty of cheer. And by the looks of it, it was a fun-filled day for all — including Lincoln’s big bro Isaac.
