The close-knit Duggar clan is getting even closer before the arrival of the family’s latest addition – just take a look at the new pic Derick Dillard, 25, posted on Instagram Friday showing wife Jill, 23, with her mom and mother-in-law, both proudly rubbing her baby bump.

The couple is expecting a baby boy very soon. As Derick’s caption notes, “Hanging out with the grandmas! #bestgrandmas #37wks”

The latest season of the family’s hit reality series 19 Kids & Counting premiered last month – and viewers got to watch as Jill and Derick listened to their son’s heartbeat for the first time.

The couple opened up exclusively to PEOPLE about their home birth prep: “We’re getting the birthing pool, things like that,” says Derick. “We have a bassinet and a crib.”

Jill’s sister Jana, 25, will be on hand, along with the midwives.

“And my sisters, mom and Derick’s mom are available as errand runners,” Jill says.
