So presh! Jessa Duggar shared an adorable new video of her son, Spurgeon, on Wednesday, March 9. In the clip, the 4-month-old makes noises, sticks out his tongue and smiles at his famous mom. 

"Showing off all his new vocabulary skills," Duggar, 23, captioned the post. "#SpurgeonElliotSeewald."

The former 19 Kids and Counting star and her husband, Ben Seewald, welcomed their first child together in November 2015. Last week, the proud parents treated themselves to a delicious dessert in honor of his four-month milestone.

"He ain't gotta clue, but Papi and I are celebrating for him over a pint of white chocolate raspberry ice cream @loblollycreamery!" Duggar captioned a family photo at the time. "#AnyExcuseForIceCream Please tell me I'm not the only one."

Showing off all his new vocabulary skills. 😜😍❤️ #SpurgeonElliotSeewald

The Jill & Jessa: Counting On star and Seewald, 20, often gush over their baby boy on their blog. "This Thanksgiving we are so happy to be parents! Children are a blessing from the Lord," they wrote back in November. "As we are embarking on this journey of parenthood, we appreciate all of your prayers. We pray that God would give us the wisdom to be good parents."
