Jill Duggar and her husband, Derick Dillard, are showing how proud they are to be parents of their son Israel David by celebrating his 1-month birthday on Wednesday.

The 19 Kids and Counting star and first-time mom took to Instagram to post a cute photo of their newborn wearing a striped onesie.

“Happy first month birthday to our handsome big guy! I hope and pray he grows up to be just like his daddy!" she wrote.

Duggar’s complex delivery of baby Israel was the center of her family’s show this week.

Dillard also posted a photo and wrote, "Happy 1 month birthday to this little man! He is growing up so quickly; it seems like just yesterday he was crying and we were changing his diaper. Oh wait...”

The Dillards shared a photo of their son just a day after she gave birth. They posted a video message to their fans from the hospital to introduce Israel and reminded everyone to watch the birth episode of 19 Kids and Counting on Tuesday, May 5.
