With only several days left to go before giving birth, Jill Duggar and Derick Dillard have been clearly prepping up for the arrival of baby Dilly.

This week, Duggar just announced that she has officially crossed the 38-week mark in her pregnancy and is getting ready to deliver her first child next week.

The 23-year-old star of ’19 Kids and Counting’ and her 26-year-old hubby are expecting to see their first baby next week, and the parents-to-be could not contain their excitement.

A source told E! News that the first-time parents have been doing several things all at once to prepare for the due date.

"You can tell they are very happy," the source said about the couple, referring to them as "humble people."

Jill has reportedly been following a pregnancy diet and combining such healthy eating with moderate exercise to utilize their benefits for the baby.

"She will be an amazing mom," the insider shared. "She is so patient, kind and very loving, and she has had a lot of practice [with siblings]!"

Dillard, who was wearing a shirt with the caption 'This guy is going to be a daddy,' posted a photo of the couple on Instagram when they recently had a Texas family vacation.

"We had a great time with family on vacation, but it doesn't look like we're going to have a Texas baby #familyvacation #babydilly #19kids," he wrote.

The Dillar couple announced that they have been expecting a little over two months after getting married last year. The parents-to-be have also announced that they will “have a midwife at home” for them to welcome the baby in the midst of family members and close friends.

“Derick will be my coach, as I like to say, so [he'll be] helping me through the process,” Duggar shared.

The 23-year-old reality star also revealed that she has been taking Bradley Method birth classes to teach the couple in understanding the childbirth process as well as the necessary strategies in delivering the baby.

Based on the Bradley Method’s website, classes are typically carried out for 3 months, teaching both parents to take part in the delivery process. These include the appropriate techniques for breathing and relaxation to handle the pain in giving birth, as opposed to relying on drugs or epidurals.

"[It's] husband-coached childbirth," Duggar added, "so that 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 comes."

The couple is also open to having more children in the future and create a big family for them.

"We're open to as many children as God will give us," Duggar said in an interview with People last year. "We believe children are a blessing from the Lord and a gift from him."
