Derick Dillard gushed over his 11-pound baby boy Israel via Instagram on Friday, May 8; "I love my little (big) guy!" he wrote

They've got their hands full! Baby boy Israel will have plenty of childhood scrapbooks to flip through when he gets older — thanks to his famous dad. Derick Dillard shared yet another snapshot of his bundle of joy via Instagram on Friday, May 8.

"Happy Friday! Israel David turned 1 month this week and is now 11lb 13oz," the 19 Kids and Counting star, 26, captioned the picture. "I love my little (big) guy! What a blessing he is! #fatherhood."

Such a darling little family! ?? @jillmdillard @derickdillard

Dillard and Jill Duggar's son wore a cute onesie for his close-up, and black mittens to help with scratching. The proud parents also stuck a "1 month" sticker on his belly.

Israel's aunt is just as obsessed with the newborn. Jessa Duggar, who is expecting her first child with husband Ben Seewald, posted a photo of her own on Thursday.

"Such a darling little family!" the 22-year-old wrote. In the sweet pic, Jill, 23, and Derick are gazing down at Israel as he sleeps.
