It's a baby Dilly bump! Jill Duggar, who's currently expecting her first child with husband Derick Dillard, is 11 weeks into her pregnancy and starting to show. Dillard posted a picture of his wife's burgeoning bump this past weekend, updating 19 Kids and Counting fans on the development of their unborn child.

"By the end of next week," wrote Dillard, "all of our baby's body parts, from tooth buds to toenails, will be developing!"

In the Instagram update, the dad-to-be, 25, shared a split-screen photo of his wife and her expanding tummy at five weeks, compared to her body at 11 weeks. "#firsttrimesterprogression #babydilly #19kidsandcounting," he added in his caption.

Duggar, 23, opened up to Us Weekly recently about her first-time pregnancy, saying the first trimester has gotten easier thanks to her "amazing" husband. "I've been very queasy… morning sickness," Duggar told Us. "But there are good days and there have been better days."

The pregnant reality star said one request Dillard truly attempts to accommodate is her aversion to specific odors. "There are certain things that Derick is not allowed to mention in the house," Duggar said with a laugh. "I asked him to have peppermint oil always on hand, because that usually is cooling and makes every other smell go away."

Joking, the future mom said she requests of her husband, "'Derick, can you please go brush your teeth like three times with mint toothpaste?! And then suck on a mint for a while before I kiss you?'"

Overall, the parents-to-be couldn't be happier with their baby news and their marriage. "He is so good! He brought me breakfast in bed a couple of days ago. He’s so sweet!" Duggar gushed to Us about Dillard. "He makes sure he gives me snacks before I get out of bed — protein snacks or saltines just so I’ll have something in my tummy before I start moving around. Grabbing me water…so he is so sweet. He is amazing… Married life is the best!"
