Tori documented her second pregnancy on social media, but it was a rough one sometimes, the new mom of two shared in August. “Im [sic] not one of those women who loves being pregnant. In fact there’s not a lot of times I do love being pregnant,” she wrote.

“I thank God for this amazing gift every single day and I know how blessed I am but it definitely hasn’t made me feel my best. I love feeling baby girl move inside me. I love sharing this experience with Zach and Jackson! I love that God has given me a gift and chosen me to be this sweet child’s mama.”

Zach and Tori first met back in 2010 when she was working on the Roloff family farm, and the two married in 2015.

“A coworker told me, ‘Zachary really thinks you’re cute, but doesn’t think you’ll ever go out with him,’ ” Tori told PEOPLE after Jackson’s birth. “Our first date lasted five hours, and we’ve been together ever since.”

Tori had previously shut down rumors that she was pregnant with her second child last October, sharing a statement on Instagram that she was not expecting.

“If and when Zach and I are blessed with another little one we will share on our own time and in our own way. We love you guys and so appreciate your love and support,” she captioned her post. “No one wants to see baby J be a big brother more than I do but let’s wait patiently together!”
