Pregnant Jill Duggar and her husband Derick Dillard vacationed in Texas ahead of their son's arrival — see her growing baby bump photo!

Next time they'll be three! Pregnant Jill Duggar and her husband Derick Dillard are making their way back home. The 19 Kids and Counting couple vacationed in Texas this week ahead of her due date.

"We had a great time with family on vacation, but it doesn't look like we're going to have a Texas baby," Dillard, 26, captioned an Instagram pic on Wednesday, Mar. 18. "#familyvacation #babydilly #19kids."'

Dillard proudly caressed Duggar's growing baby bump while standing near a lake. Ready for his son's arrival, he wore a "Rookie Dad" baseball cap and a red T-shirt that read: "This guy is going to be a daddy." 

Earlier this week, Arkansas native Duggar shared one of her final baby bump photos via Instagram. "38 weeks 5 days," she wrote on her handy chalkboard.

The couple's first child may share the same birthday month as Dillard. On Mar. 9, Duggar celebrated her hubby's special day with a sweet Instagram message.

"Happy birthday @derickdillard to the man of my dreams! I love you more than ever and pray God continues to make you more like him every day!" she captioned a photo. "You're the sweetest, most Godly and caring husband! I'm so blessed to be married to you!"
