COWETA COUNTY, Ga. — 11Alive first introduced you to the Miller quadruplets – three boys and one girl – shortly after their birth in December 2016.

Their delivery was special because the quadruplets were conceived naturally – without the use of any fertility drugs.

Nearly three years since our initial story, Brandon, Kenlee, Bryant and Brayden are so big now.

The quadruplets celebrated their second birthday back in December. Their big brother Bentlee is growing up too. He’s now 6.

“Ah man! It’s definitely been life-changing. When we go out it’s crazy. Everybody wants to take pictures. Everybody stops,” said their mom, Kortney Miller.

This big family has been the talk of the town since our first story back in 2016.

“We had a lot of support. Between social media, the news and family,” Miller explained.

The Miller Quads' delivery was something so rare that the odds are only one in 700,000. Their delivery was a first for Piedmont Newnan Hospital.

“It’s hectic [now], but you know we are really on a schedule. Like they know what we do when we get up. Eat breakfast, things like that. They take their naps during the day and play. It’s every day. It is the same thing every day,” said Miller.

“Bentlee is a good big brother,” she mentioned.

Miller says the kids keep her pretty busy and she’s also been able to connect with other quad moms.

“We got a quad page on Facebook. Just quad moms. So, we all keep up with each other and talk about each other’s growths and things that their kids are doing. I look at their stuff just because they have quads. Like okay, I got to look forward to this. I got to look forward to that. It’s not easy, but it’s fun,” she said.

“I wouldn’t trade them for the world. I love them. I can’t imagine life without them,” Miller mentioned.

Miller says her five kids have been the biggest blessing. You can keep up with the Miller quads on Facebook.
