"19 Kids and Counting" star Jill (Duggar) Dillard and her husband, Derick, are just one week away from welcoming their son, who they refer to as "Baby Dilly," into the world, and have shared how they are preparing for his birth.

On Monday, Jill, 23, posted new pic of her growing baby bump while holding up a chalkboard with the words "38 weeks 5 days,"

"We are getting so close!!!" said the caption on the Duggar family's Facebook page. "If you're pregnant will you post your picture here just like Jill has been? We would love to see it and will pray for you and your sweet baby, too!"

The soon-to-be parents, who attended a baby shower thrown in their honor on Feb. 28, have said they are planning a home birth for their son with the help of Jill's sister, Jana Duggar, and a midwife.

"Derick will be my coach as I like to say," Jill said back on October. "So [he'll be] helping me through the process...My sisters, mom and Derick's mom are available as errand runners," she added.

"We're getting the birthing pool, things like that. We have a bassinet and a crib," added Derick, who has carefully tended to his wife as her due date draws closer, even unning downstairs in the middle of the night to get her snacks. "He is the sweetest guy," Jill said. "We are so excited and very happy."

To ensure both she and the baby are healthy, Jill has maintained a steady diet of fruits, vegetables and lean meat, and has continued with moderate exercise throughout her pregnancy, according to recent Instagram photos.

"She will be an amazing mom," a family friend told E! News. "She is so patient, kind and very loving, and she has had a lot of practice [with siblings]!"

Although she has enjoyed her pregnancy, Jill says she's counting down the days until she feels better: "I have been having a few Braxton Hicks contracts here and there and the little guy is moving around a lot," she told the AFP last month.

Once "Baby Dilly" arrives, Jill and Derick say they hope to have many more children.

"We're open to as many children as God will give us," Jill told People last year. "We believe children are a blessing from the Lord and a gift from him."

The current season of "19 Kids and Counting," which airs every Tuesday night on TLC, will focus on Jill's pregnancy, her marriage to Derick, and her sister Jessa's engagement to Ben Seewald and the pair's subsequent wedding.
