Those Duggars sure can pump out the babies. Now Josh Duggar is expecting number four.

19 Kids and Counting co-stars Josh Duggar and his wife Anna have revealed that they are expecting their fourth child.

“One of the things that we’re really thankful for this [holiday] season, is that we’re expecting. I’m nine weeks pregnant, and having a lot of morning sickness, so it’s difficult. But it’s good, because I know that good things are happening.” Anna said on a TLC promo video.

The couple said that they are still trying to figure out whether to have a home birth, hospital birth, or use a birthing center. They now live in Washington, D.C., far from their past locale in Arkansas where they the support of family and friends.

The pair already have one five-year-old daughter, Mackynzie, and two sons Michael and Marcus, ages three and a half and 18 months, respectively.

Thx 4 all the well wishes! Every life is precious & a gift from God – we're so #blessed to have baby #4 on the way! #4andCounting #19Kids

The Duggar clan are part of a fringe Christian movement that values having many children. Family patriarch Jim Bob Duggar and his wife Michelle have 19 kids of their own. Daughter Jill and her husband Derick Dillard are expecting their first child.

In addition to baby-making, the Duggars have a strict code of moral rules. The daughters ahve been forbidden from kissing or hugging a boy full-on during courtship. Daughter Jessa Duggar and new husband Ben Seewald famously withheld even their wedding kiss until they were in private.

But the Duggars’ morality code has run afoul of some. Mom Michelle Duggar caught flak for recording an offensive robocall campaign message that claimed transgender persons are convicted sex offenders who simply want access to girls’ bathrooms.
