The couple is already parents to daughter Henley Grace "Gracie", 6, and son Hendrix Douglas, 3.

Jamie teased the big news on Monday, sharing a video to her Instagram with her family of five. "Finally! I’ve waited over three years for this!🙏😭🥳 So excited to share our BIG ANNOUNCEMENT with you!🥳," she wrote in her caption.

"We are so excited to take you on this new journey with us! Thanks for being here and celebrating with us! We love you!!! 💜 #bestfrans," she wrote, directing her followers to her YouTube channel.

In 2019, Jamie and Doug chatted with PEOPLE as they shared scenes from their sex reveal before welcoming their son.

“Doug instantly cried tears of joy. Our first baby was a boy, but we lost him at 17 weeks. Of course he loves our daughter, but he’s wanted a baby boy so badly for so long. This is truly an answered prayer for us,” Jamie told PEOPLE.

“For me, I can honestly say I was and I am still just praying for a happy and healthy baby. I didn’t care if it was a boy or girl — please just stick and be healthy. Of course, Doug wants that too, but he was begging God for a boy who’d stick and be healthy.”

Jamie and Doug revealed they were expecting again in September 2019, when the mother-to-be celebrated having a “viable pregnancy” at five weeks along after previously losing their son Johnathan Edward at 17 weeks gestation.

They went on to welcome Gracie after the loss, in August 2017. Jamie then experienced a chemical pregnancy in 2018, and a miscarriage at 10 weeks along in January 2019.

“I thought having a family would be very easy, so my own misconception about myself was [that] I would be able to have a family very easily,” Jamie said in May 2019 on the Share Your Shine podcast. “Come to find out, it’s not as easy … and come to find out, one in four women will have these same issues.”
