Two boys and counting: Pregnant Jill Duggar reveals that she and husband Derrick Dillard are expecting a son

• e-mail

One month after announcing that she was pregnant, Jill Duggar is revealing that she and husband Derrick Dillard will be welcoming a baby boy - again.

It will be the second child for Jill, who welcomed son Israel into the world back in April of 2015 after a difficult pregnancy in which doctors were forced to perform a C-section following a 70 hour labor.

Jill was 42 weeks pregnant at the time.

Despite that experience, Jill still said in a video posted by TLC that she  and Derrick are 'so excited' to be parents again and cannot wait to welcome their newest family member this July.

'We're really excited about having another son, and I know that Israel and this one will be best friends,' said Jill.

The 25-year-old reality star also said that she 'had morning sickness in the first trimester' but is now feeling much better in [her] second trimester.'

Growing brood: It will be the second son for the couple, who welcomed their first child Israel in April of 2015 (Jill and Israel above earlier this month) 

On the way: Jill revealed last month that she is pregnant with her second child, who is due in July

The baby news has proved to be a bit confusing for son Israel according to Derrick. 

'Israel can't really understand what's happening but he's excited because other people are excited,' said Derrick. 

Derrick also said he was excited about Israel having someone around to interact and play with come July, and maybe help him learn to share.

Jill and Derrick's big reveal comes just a few days after they joined the March For Life in Arkansas last week.

Derrick shared a photo of himself with his wife at the rally on Instagram, writing: 'This week is the 44th anniversary of Roe v. Wade, and we mourn those nearly 60 million people who have lost their lives to abortion. 

'Even sadder is that these executions are still perfectly legal according to man's law and will continue to remain so if people don't stand up for righteousness' sake! #overturnroevwade #marchforlife'

Beliefs: Derrick wrote that he and Jill 'mourn those nearly 60 million people who have lost their lives to abortion,' which he stated was the same as 'execution'

Jill shared her pregnancy news just days before Christmas last month on the Duggar family website.

'Words can not describe how excited we all are that God has blessed us with another precious gift!' wrote Jill and Derrick at the time.

'We are eager for another sweet Dillard baby to join our lives, and we know Israel will be a great big brother.'

They also posted a photo standing with their son Israel who held up a sign reading: 'I'm being promoted to big brother.'

Derrick joked about the post on his Twitter account, writing that there was some exciting news to share' before stating: 'If you guessed we're getting a new puppy, then guess again!'

His tweets after that were not so jovial though, including one in which he shared his excitement and wrote about how 'blessed' he was but then included an image that showed the outline of a pregnant woman's body.

An arrow pointing to the fetus drawn on the body read, 'Someone else's body. And underneath the woman it said 'NOT your body.'

That tweet was quickly deleted however and replaced with one that had the same image but no mention of Derick's baby joy.

'You shall not murder,' it said up top, attributing the quote to Exodus 20:13. Then beneath that line it read: 'Abortion = murder = sin' 

Tough time: Jill gave birth to Israel via C-section after 70 hours of labor in her 42nd week of pregnancy (above)

More Duggars: Jill's sister Jessa (above) is also pregnant with her second child, and is due any day now

In addition to his big brother, Jill and Derrick's baby boy will also have a new friend waiting for him when he arrives as Jill's sister Jessa and her husband Ben Seewald are expecting their second child any day now.

Jessa has a son Spurgeon who she gave birth to in November of 2015, just a few months after Jill welcomed Israel.

The sex of Jessa's second child is a mystery however, as she and Ben made the decision to keep it a surprise. 

Jessa's son or daughter will the seventh grandchild for Jim Bob and Michelle Duggar, who in addition to Israel and Spurgeon are grandparents to Josh and Anna Duggar's sons Marcus and Michael and the couple's two daughters Meredith and Mackynzie. 

Josh made a decision similar to his parents and used the same letter for the names of all his children, choosing 'M' instead of 'J' like his parents.

Jessa will therefore be the first to break this tradition when she gives birth shortly, as she has revealed in the past that she will not be giving her children the same first initial. 

Back when Jessa was about to give birth to her first child, Jill wrote about what a joy motherhood was in an open letter to her sister, despite her difficult pregnancy. 

'I’m so excited to both be on this motherhood journey together! I pray our boys will love Jesus with their heart, soul, mind and strength and love others more than themselves!' wrote Jill, who was doing missionary work in central America at the time. 

'We will have to let them FaceTime frequently while we are down here. It will be so fun to see them experiencing things and going thru similar stages within a few months of each other. I’m sure since they were about the same size at birth they’ll be sharing clothes too.'

Jill got pregnant with Israel almost immediately after she was married to Derrick in 2014, but then struggled to get pregnant again with her second child in the two years since giving birth. 

Jessa and Jill may soon be welcoming another sibling into the mom club too now that sister Jinger has tied the knot, marrying Jeremy Vuolo last November in a ceremony that was attended by close to 1,000 guests.

And another Duggar wedding could be on the horizon as well, with Joy-Anna Duggar announcing in November that she is courting Austin Forsyth.

Joy-Anna, 19, has been friends with Austin for 14 years.
