It'll be a boy for Zach and Whitney Bates!

On Wednesday, Whitney, 27, revealed the sex of her baby on the way with husband Zach, 31, in a social media post shared to the couple's joint Instagram account.

Featuring the soon-to-be family of six all dressed in coordinating ensembles as they posed before a blue, spray-painted backdrop, the pair detailed more about the exciting news in the caption of their post.

"IT'S A BOY!!!!!💙🎉 Jayden Carl is on his way, and we're all counting the days to hold and cuddle the newest baby Bates! 🤩," the couple wrote. "When we told the kids we were expecting, Bradley talked about all the times he had prayed for a baby brother! He prayed every single night that God would answer his prayer and give him a brother, and seeing the joy in his eyes when we shared the news with him was priceless."

"We all couldn't be more thankful for this newest blessing!!," the pair added. "We are extremely excited and June just can't get here soon enough!"

During her chat with PEOPLE last year, Whitney also explained that her pregnancy had not been without its challenges, as her husband was diagnosed with the coronavirus — and ultimately, she got it too.

"Shortly after we found out we were pregnant, Zach unfortunately contracted COVID-19 at his work and I ended up testing positive as well," she said. "It was a rough couple weeks for our family, with a lot of prayers going up for the new baby, but we thankfully have all recovered and feel healthy again."
