Original Story Appears Below

Jill Duggar is more than a week past her original due date, and the rumors regarding her first-born’s anticipated arrival are swirling. While the Duggar family has not commented on the speculation that Jill, 23, is either in labor or has given birth to her and her husband Derick Dillard’s little one, that hasn’t stopped “19 Kids and Counting” fans from speculating themselves.

Wednesday morning, Derick, 25, posted a cryptic message on Twitter, quoting a biblical passage about labor just days after Jill revealed she was having Braxton Hicks contractions:

The biblical quote has resulted in a social-media frenzy. While some “19 Kids and Counting” viewers have shared they believe Derick’s post refers to Jill going into labor, others have speculated it means Jill has already given birth.

And that’s not the only thing fans of the TLC series are gossiping about. Derick’s decision to share that particular biblical passage has led some to speculate “Isaiah” is the name of the couple’s son. In recent months, he and Jill have simply referred to their child as “Baby Dilly.”

The couple last spoke about potential baby names with People magazine in October. “We are not going to do a letter theme,” said Jill, whose 18 siblings all have names beginning with the letter “J.” However, she said, “We may do some kind of theme, like family names.”

Jill last updated her fans on her pregnancy Wednesday. “Getting some things done while anticipating the arrival of our little man any day!” she posted on Instagram alongside a photograph of herself appearing to do paperwork.

Currently in its ninth season, “19 Kids and Counting” will feature a special on Jill’s highly anticipated delivery next month. TLC recently confirmed the two-hour episode will include her mom Michelle Duggar’s best parenting advice as it celebrates the arrival of the baby.

While fans await the baby news, they can catch up with the couple and the rest of the Duggar brood on “19 Kids and Counting.” New episodes are shown on TLC Tuesdays at 9 p.m. EDT.
