Jill Duggar (R) and her husband Derick Dillard (L) are due to welcome their first baby later this month. TLC

Jill Duggar and her husband Derick Dillard are weeks away from welcome their first baby. Ahead of the newest “19 Kids and Counting” cast member’s arrival, Jill took a moment to pose with her mom, Michelle Duggar, and mother-in-law on Saturday. The TLC reality star’s husband shared the touching image on social media.

“Hanging out with the grandmas!” Derick, 26, captioned the image of his mom Cathy and Michelle, 49, touching Jill’s third trimester baby bump. The dad-to-be also included the hashtag “#bestgrandmas” alongside the candid shot.

Michelle later shared another photo from the get-together -- which occurred in honor of Derick’s birthday Monday -- on the Duggar family’s Facebook page. “We had an great time tonight celebrating Derick’s 26th birthday a couple of day early,” Michelle captioned an image of herself posing with her husband Jim Bob, Jill, Derick and Cathy. “It is really amazing when your baby girl is getting ready to have her own ‘birth’ day,” she added.

Prior to Derick’s birthday bash, Michelle posted about her daughter hitting 37 weeks gestation. “This little Duggar grandbaby is about the size of a large cantaloupe and is practicing for life outside the womb by sucking, turning and breathing!” Michelle wrote March 4. The post was followed by an image of Jill showing off her baby bump and holding up a sign indicating she was 37 weeks and 1 day along. Michelle concluded her post by telling fans she would meet Jill and Derick’s little one “very soon.”

The expectant couple – they’re due to welcome their son March 24 -- have also been spending time with their church friends in recent days. On Sunday, Jill, 23, shared an image of herself and Derick enjoying their second baby shower at Olive Garden with member of their congregation. “We were so blessed!” Jill said of the event.

Jill's pregnancy is one of two big storylines on Season 9 of TLC's “19 Kids and Counting.” Previous episodes featured the couple visiting Jill's midwife for an ultrasound, Jill and Derick trying their hand at parenting, and the mom-to-be announcing her pregnancy to her family. A future episode might even show the arrival of the little one which the couple confirmed was a boy in October.

While Michelle appears thrilled about the impending arrival of Jill’s first baby, it isn't the only grandchild she is expecting in 2015. In December, her oldest son Josh’s wife Anna revealed she was pregnant with their fourth baby. The couple recently announced the child's gender ahead of Anna's June due date.

Catch up with Jill, Derick and the rest of the Duggar clan on “19 Kids and Counting" Tuesdays at 9 p.m. EDT on TLC.
