Jessa Duggar has been enjoying time with her newest nephew, Israel David Dillard. The pregnant 19 Kids and Counting star took to Instagram on Saturday, April 25, to share pictures of the Duggar family's latest addition. 

"This little man is too cute! #IsraelDavidDillard #BabyDilly @jillmdillard @derickdillard," Jessa captioned four new shots of her sister Jill Duggar's baby boy. 

Jill and her husband Derick Dillard welcomed their little bundle of joy on April 6, and the family has been happily posting photos of the infant boy on social media ever since.

"Not everything went as expected," Jill said in a video the couple recorded at the hospital after she gave birth. "We were reminded of the verse that the Bible talks about where man plans his way but the Lord directs his steps. We were encouraged by that and yeah, he's just a handsome little fellow."

Jessa also posted an image of the new parents cradling their son on a couch, writing, "Such a sweet little family! @jillmdillard @derickdillard."

Jill's younger sister is expecting her first child on Nov. 1, which is her one-year wedding anniversary to hubby Ben Seewald
