Whitney's pregnancy comes after she had a miscarriage in 2018. She and Zach shared about their heartbreak and recovery on "Bringing Up Bates."

Whitney opened up on Instagram after her pregnancy announcement, calling the miscarriage "a valley that has drawn us closer."

"Last summer Zach and I experienced a miscarriage and our hearts were broken, although we knew we could trust God. It was a valley that has drawn us closer & it has melted our hearts to watch our children pray for another sibling! God has answered their tender prayers and we are all flooded with joy and gratefulness!" she wrote.

"The main topic around the house has been about the new baby coming and whose gets to hold it first! Oh and the tiebreaker ... whether it’s a boy or girl! Lol! Our hearts are SO full and we can’t thank all of our family, friends and followers for all of your love!"
