Jill Duggar is counting down the weeks to the arrival of ‘Baby Dilly.’ That’s the nickname she and husband Derick Dillard gave their unborn son shortly after learning that the 19 Kids and Counting star was expecting. Now at the 35-week mark, Jill and Derick will soon celebrate the birth of their baby.

Earlier on Tuesday the Duggar family’s Facebook page featured a new picture of Jill Duggar along with little sister Jordyn. Jordyn was trying to look like her older sister, by hiding a pillow underneath her top.

Michelle Duggar is no doubt very excited about having yet another grandchild, and therefore loves sharing all of these precious moments on social media.

Last Thursday, the Facebook page featured a picture of Jill Duggar holding up a chalkboard indicating she’s on the home stretch of her pregnancy.

Jill Duggar and Derick Dillard tied the knot in June, and didn’t waste any time starting their family. Sister Jessa Duggar married Ben Seewald in November, and fans are hoping to hear of her first pregnancy any day now as well. Jessa and Ben recently said they plan to both adopt and have biological children if that is God’s will.
