Countdown to Baby

How Jill and Derick Dillard Are Getting Ready for Their Little One?

Get out the booties, blankets and birthing tub, "Baby Dilly" is weeks away.

The newest addition to the expansive Duggar clan featured on TLC's hit reality show 19 Kids & Counting is due in March – and his parents Jill and Derick Dillard are getting into ready-mode, they tell PEOPLE exclusively. "Baby Dilly" is the nickname the couple has been calling the baby throughout her pregnancy.

"I feel great, I feel really good," says Jill, 23. "He's moving around a lot and doing a lot of rolling."
She and her husband Derick, 25, revealed her pregnancy exclusively to PEOPLE two months after their June 21, 2014, wedding. They attended birthing classes and now that she's at 35 weeks, they're getting the house ready for their planned home birth.

"We're getting the birthing pool, things like that," says Derick. "We have a bassinet and a crib."

While Jill has years of experience with babies as a sibling to 18 kids, she is also a midwife. Along with her midwives, her sister Jana, 25, will be available for support, she says.

"And my sisters, mom and Derick's mom are available as errand runners," she says.

Jill's younger sister Jessa, 22, who was married Nov. 1, and her husband, Ben Seewald, 19, shared their hope to adopt children as well as have biological children of their own – something that Jill and Derick have also said they would like to do. But in the meantime, they are ready to welcome their new boy into the world.

Derick, who has just one sibling – his younger brother, Daniel – says he is looking forward to both of them changing their first diaper.

"I think my brother will be a great uncle," Derick says. "He has as much baby experience as I do, but he has lined things up already, planning to take our son camping someday. We'll both get to change our first diaper."
