Another kid will soon be livening up the household of Willie and Korie Robertson from "Duck Dynasty," and the Robertson family could not be happier.

Korie opened up about their plans to adopt another young boy on her Instagram account (@bosshogswife). She shared a photo of the Robertson children with a smiling young boy in the middle.

"We've had lots of questions about the cute kid popping up in our photos lately," she wrote. "We are excited to be in the process of adopting a new son! He's been with us since May, but we wanted some privacy and time for him and our family to bond before telling the world (It's a bit of an adjustment coming into this big, crazy family, ha). He's amazing, and we are all so thrilled to have another kid around the house. Couldn't keep the good news to ourselves any longer! We appreciate your prayers and support for our family! Love, The Robertson's."

During an interview with Entertainment Tonight, Korie shared that they got him "at the end of the school year" and that the young boy actually attended John Luke's wedding to Mary Kate McEacharn. He "walked my grandmother down the aisle," said Korie.

She and Willie are parents to three biological kids—John Luke, Sadie, and Bella, and two adopted children—Will and Rebecca Lo.

Because their kids are all so different in personality, the Christian couple had to employ unique parenting methods. "Some of our kids are one way, some of them were hard-headed,msome of them were not. Some of them were super sensitive, so you have to take all of that into effect," Willie earlier said. "I could look at Sadie one way, and she would start cryin'—like that!—it wasn't a spanking or anything like that, she was so sensitive. And John Luke was very hard-headed, and his brother, Will, was very hard-headed."
