Jill Duggar and husband Derick Dillard are about to be second-time parents! The couple is expecting their second child this July, another baby boy. In the Dillard family's official website, Jill and Derick excitedly revealed the name they've chosen for their baby number two.

In July, Samuel Scott Dillard will be the newest member of Jill and Derick's growing family. Their first son, Israel, is now two years old and will very soon be a big brother!

"We can't wait to welcome him to the world," the excited parents wrote on their family blog.

Jill and Derick announced that they were once again pregnant last December 2016.

In January, they revealed that they were expecting another baby boy.

The "Counting On" stars are currently back in the United States from their mission field in Central America. They arrived a few days before Joy-Anna Duggar's wedding to Austin Forsyth last May 26, where Jill reportedly stood as the matron-of-honor.

'Counting On' Season 3

Jill and Derick made their baby name reveal just six days before their reality series "Counting On" Season 3 premieres on TLC. Joy and Austin's wedding special will be shown in its pilot episode on June 12.

The season's trailer also hints of more Duggar family developments. Fans will see Jinger Duggar as she experiences being a new wife to husband Jeremy Vuolo. The two have been married late last year. More than six months into their marriage, Jinger and Jeremy have yet to announce a much-anticipated pregnancy.

In the "Counting On" sneak peek, Jill, Jessa, Joy-Anna, and Jana Duggar are seen chatting with Jinger via Facetime. The Duggar sisters ask Jinger if she's pregnant yet, and force her to take a pregnancy test.

Joe Duggar's courtship with Kendra will also be featured in the new season. In the clip, he is seen asking Kendra's dad if he could start a relationship with her. Joe and Kendra just recently announced their engagement, on the same day as Joy and Austin's wedding.

Jill and Derick's missionary work will also heavily play out. The two are seen mulling about their decision to go back to Central America because of the dangers it entails for their family. Just last month, Jill wrote on her blog that their friend was brutally murdered in Central America and asked prayers from her supporters.

Meanwhile, there's no sign whether or not their eldest brother, Josh Duggar, will appear on "Counting On" Season 3. Josh has been staying away from the media since his child molestation charges two years ago. However, just last week, Josh made his return on social media when the Duggar family posted a picture of him and wife Anna during their son's fourth birthday party.

"Counting On" Season 3 will air on June 12 on TLC.
