Just last week, the Duggar family posted a photo on Facebook comparing the then-overdue Anna, 27, with her sister-in-law Jessa (Duggar) Seewald's baby bump.
The baby news comes three days after TLC announced they were canceling19 Kids and Counting, the reality show that made the Duggar family famous. Josh has been at the center of the controversy since news of his molestation scandal came to light in May.
Jessa and sister Jill (Duggar) Dillard -- who is currently in Central America with her husband Derick Dillard and their son Israel on a Christian mission -- were two of the girls Josh was accused of molesting as a teenager.
Anna has stood by her man, and the family appears to be trying to move past the scandal as best they can.
Josh and Anna recently moved back to Arkansas. Learn more about their move in the video below:
