Ben jokes about passing off their baby to 23-year-old Jessa when their child needs a diaper change, but quickly changes his tune in the cute preview.
"Just kidding, you'll probably pass the baby off to me," Ben tells a then still-pregnant Jessa. "You'll probably be up at night with the baby, so, I gotta contribute somehow."
"Yeah, you will," Jessa smiles.
The clip also features Jessa's sisters -- Jill, Jinger, and Jana -- having a difficult time buying clothes for the baby without knowing its gender yet.
"We're trying to be really creative with the items we found that were gender neutral," Jinger says. "It's really hard because some things are brown, and you're like, 'Well if you threw a bow on it, it could work for a girl.'"
"We're loving all the cute hand-me-down outfits from Israel!" Jessa Instagrammed on Thursday. "Little overalls are so adorable on baby boys!"
And it turns out she had no reason to worry about her 20-year-old hubby slacking on daddy duties. She recently gushed about his parenting skills while sharing an adorable photo of Ben kissing baby Spurgeon on the forehead.
"I'm so grateful to be married to such a sweet, godly man!" Jessa wrote. "These past three weeks have been so precious to me as I have watched you love and care for our son. From his middle of the night diaper changes to his sweet cuddle times with daddy, it melts my heart to see the interaction between you two! You're such a good daddy!"
