Fans of '19 Kids and Counting' will be excited to learn that Jill Duggar showed off her growing baby bump in a recent picture taken during her Thanksgiving Day celebrations with husband Derick Dillard.

The reality star spent Thanksgiving with her husband's family and posted a photo on Instagram with the caption: "So many blessings to count this Thanksgiving...Mama Cathy is well, best hubby in the world, expecting a son, God's mercies are new every morning! #happythanksgiving."

Dillard shared the original photo and wrote, "So thankful that the Lord has healed mom and we can have Thanksgiving dinner with her this year! #beyondblessed #family #bestmom." For those that may not know, Dillard's mother has been fighting cancer since September.

A few weeks ago, the couple shared their baby's first ultrasound picture on Instagram and talked about the pregnancy in an interview. "I actually got to feel him move a couple times this week," Duggar said.

"I had to give him a little squeeze but then he kicked back. It was really exciting," Dillard added, according to International Business Times.

The baby is due in March 2015 and the couple has expressed their happiness in starting a family and their willingness to share the journey with their fans.

Amidst the pregnancy excitement and holiday preparations, Dillard's grandmother passed away a week before Thanksgiving. He expressed his gratitude on Instagram and posted a picture of his grandma with the caption:

"So grateful that Jill and I got to speak with my grandmother this week before she passed away earlier today. You will be greatly missed Grandma Vergie, but we're looking forward to seeing you in Heaven before too long!"

Dillard mourned the loss of her husband's grandmother and reposted the photo with the caption: "Grandma Vergie, you will be greatly missed! Derick and I are so grateful we were able to speak with her recently before she passed away today."
