Which Teen Mom 3 Baby Just Turned 16 Months Old? (PHOTOS)

We're obsessed with Mackenzie Douthit's kiddo, Baby Gannon. Mostly because he owns cowboy boots and rides around on a miniature pony. Keep livin' the dream, buddy.

"16 months old today:)" Mackenzie posted on January 13 along with a picture of Gannon chilling out in a saddle. "#bigboy #littlecowboy."

Can you believe this dude is almost a year and a half? Before we know it, he'll be saddling up for his very first rodeo! Gannon has so much to look forward to this year — not only are his parents getting married, he's moving to San Diego, California, where we assume he'll become a surfer.

Hang ten forever, Gannon!
