The Duggar family provided baby updates on their blog on Sunday, and revealed the due date for Anna's new addition.
Anna is the wife of eldest Duggar child Josh, and is nearly 17 weeks pregnant. The couple has three other children.
The Duggars revealed that Anna is due on July 10, and they are not ruling out multiples. They also expressed excitement at learning the sex of the baby, or babies, in the coming weeks.
Josh's sister, Jill, is expecting her first child with husband Derick Dillard in eight weeks. Their baby boy is due on March 24. The family also said that another family member could add to the Duggar brood this year.
"In 2015, Jim Bob and Michelle Duggar will welcome at least two more grandchildren into their family," they wrote.
"If Jessa and Ben Seewald make a pregnancy announcement, or if Josh and Anna Duggar find out they are having multiples, the Duggar clan could grow even more."
When the family announced Anna's pregnancy, they also asked for prayers. Anna, who was nine weeks pregnant at the time, was experiencing a lot of morning sickness.
"It's difficult, but it's good because I know that good things are happening," she shared.
The pregnancy is also her first away from Arkansas.
"The whole support group that we had in Arkansas, we don't have here," Josh said of the family's move to Arkansas. "We've made a lot of friends and all that, but thinking of having a baby in D.C. is a lot different."
The "19 Kids & Counting" family celebrated their growing clan on social media.
"We are so excited for them and for our family as a whole," they wrote. "Every life is precious and designed with purpose and a God-given destiny. Rejoice with us and please pray for Anna and the baby in the months to come!! Yeah!!!"
