"19 Kids and Counting" star and mommy-to-be Jill Duggar should pop anytime soon. But while waiting for their little one to arrive, the 23-year old reality star and her husband are spending great moments together. Recently, they celebrated what they call their "9 monthiversary" as Mr. and Mrs. Derrick Dillard. 

"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 daddy-to-be captioned a collaged photo of his wife and her big baby bump, himself wearing a blue shirt that says "#newdad," and a special mug with the words "dad-to-be loading in progress." 

Dillard is also ready in the event Jill goes into labor. The couple took classes from Bradley Method in preparation for the big day. 

"It's husband-coached childbirth," Jill told E! News. "He can know how to help me in labor and in pregnancy —and that's what I want the most, is [for] him to be able to know what to do when that time comes." 

Even with Jill's due date inching closer, the couple managed to travel to Texas. They shared a photo of themselves all smiles with Derrick laying a hand on his wife's big baby-ful tummy and wearing a T-shirt that again shows how proud he is to be a dad. 

The snap was shared in Instagram by Dillard himself with the caption: "We had a great time with family on vacation, but it doesn't look like we're going to have a Texas baby." 

The folks from the hit TLC reality show really love to keep their fans up to speed through social media. Through Instagram again, Jill's brother-in-law Ben Seewald (whose wife Jessa is frequently dragged into pregnancy rumors) posted a photo showing the "fam sharing a meal" at Jill and Derrick's home. The get-together was what he called "#fellowship."
