It's another reason to celebrate!
To mark the occasion, the mom-to-be showed off her very large baby bump at 39 weeks pregnant, while Derick showed off just how much he loves her and is excited to be a dad.
Sporting his hashtag "new dad," shirt, Derick wrote, "Happy 9 monthiversary!!!" to Jill before adding, "A LOT has happened since June 21! I am blessed beyond measure and every day is even better with you baby! You're my best friend, and I love you with all my heart!"
The newlyweds were also just in Texas less than a week ago. Derick posted on Instagram, "We had a great time with family on vacation, but it doesn’t look like we're going to have a Texas baby."
As Jill nears her due date, it looks like the couple is doing their best to stay surrounded by family, joining her sister Jessa and her new husband Ben Seewald for a family dinner on Sunday. Ben posted this snap from Jill and Derick’s place with the hashtag "fellowship."
