Inside the Lives of Kim & Kroy's Kids Today: "So Happy"

   

Kim Zolciak and Kroy Biermann's kids are getting older! The Real Housewives of Atlanta alum is a mom of six children with her ex-husband and is showing just how much they continue to grow right in front of their eyes.

Kim took to her Instagram Story recently, where she showed what her second eldest son, Kash Biermann, looks like today. In the photo, Kash can be seen sitting on a chair, in the middle of a room, wearing a black t-shirt, black bottoms, and a matching hat with the word "Good" embroidered on top of it. Even the Don't Be Tardy alum could not get over how grown-up her son looked in the photo. "He's only 12!" she wrote over the snapshot.

It's so hard to believe that Kash is now 12, after Kim gave birth to him on camera during Don't Be Tardy Season 2, Episode 1. Now, he's almost a teenager and playing football, just like his former NFL player dad (more on that down below).

Who are Kim Zolciak and Kroy Biermann's kids?

Kash isn't the only child that Kim is so proud of, as she has five more children that she shares with Kroy. Kim is the mom to 28-year-old daughter, Brielle Biermann, as well as her 23-year-old daughter, Ariana Biermann, from a previous relationship. Kroy legally adopted both girls in 2013, which was documented during Don't Be Tardy Season 2, Episode 12.

Kim and Kroy welcomed their first son together, 13-year-old Kroy Jagger "KJ" Biermann, in May 2011. 12-year-old son, Kash Kade Biermann, followed suit and was born in August 2012. The former couple expanded their family for the last time in November 2013 when Kim gave birth to their twins, Kaia Biermann and Kane Biermann, who are now 11 years old.
