It's Mackenzie Douthit!
This adorable baby is none other than Gannon McKee, Mackenzie's 1-year-old son.
We first met Mackenzie and Gannon on Season 4 of 16 and Pregnant earlier this year, but their reality TV run is far from over — these country cuties will soon grace our small screens on Teen Mom 3!
