There was a time when the Duggar pregnancy announcements happened so frequently that it was hard to keep up.
These days, however, the deluge of Duggar offspring has slowed to a trickle.
At the moment, multiple Duggar women are rumored to be pregnant, but no official announcements have been made.
What gives? Well, fans have a theory as to what might be holding up the parade, as well as a few predictions about who will be sharing their big news next.
Take a look:
The Duggar Daughters
Aside from Jana, all of Jim Bob and Michelle's adult daughters are married with children these days.
Jinger Duggar is the latest to bring a bundle of joy into the world, having welcomed little Felicity Vuolo in July.
A Race to the Finish
Of course, Jinger is the most recent new mom by only a few weeks. Joseph Duggar and Kendra Caldwell welcomed a son named Garrett in June.
And Baby Makes Three
Joy-Anna Duggar welcomed a son named Gideon Forsyth back in February, and that's it for the Duggar births of 2018.
Not Too Shabby
That may sound like quite the productive year in terms of procreating, but Michelle and Jim Bob probably thought their kids would be even more fruitful by now.
The Tipping Point
After all, 2018 marks the first year in which more than half of their kids will reach the age of 20 or older by year's end.
