Jill Duggar of 19 Kids and Counting fame recently announced that she and her husband of two months, Derick Dillard, are expecting their first baby. Now it seems she has named–or nicknamed, actually–her prospective bundle of joy.

Jill Duggar and Derick Dillard tied the knot back on June 21st. Friends, family members, and fans were no doubt thrilled to hear news of her pregnancy just a month or so after their big day.

Derick and Jill Dillard shared word of their impending parenthood via an adorable photo on Instagram.

“We’re expecting!!! So grateful to God for this new little blessing!!! #babydilly #firsttimeparents #sogratefultoGod #derickdillard #jillmdillard,” she captioned the shot.

It seems Baby Dilly is how Jill Duggar and her husband will refer to their unborn baby until he or she is born.

The happy couple first shared word of their pregnancy with People magazine.

“We’re having a baby!” Jill said. “We are so excited.”

“About 30 days after Jill and Derick got married they gathered everyone in the living room and shared the news,” proud Grandpa Jim Bob Duggar said. “Everyone was clapping and cheering, and we were in shock, too.”

It will certainly be fun for fans of 19 Kids and Counting to watch the progression of Jill Duggar’s pregnancy throughout the next several months. There will likely be baby showers and shopping trips, and lots of words of wisdom shared by Jill’s mom Michelle Duggar.

Jill Duggar and Derick Dillard’s baby will be born into a huge, loving family full of aunts and uncles–as well as cousins, too. The oldest of the nineteen Duggar kids, Josh Duggar, has a family of his own.
