They’re getting ready for baby!

Just one month after Jill Duggar confirmed she’s pregnant with baby No. 2, the soon-to-be mom-of-two revealed the gender of her second baby — and it’s a boy!

Jill and her husband, Derick Dillard, made the announcement by posing with their one-year-old son Israel and another outfit for a little boy. They surprised their family with the big news by hosting a scavenger hunt with her younger siblings. So cute!

This is the second child for Jill and Derick, who welcomed Israel in April 2015. They announced their pregnancy just before Christmas, saying, “We are so excited to be expecting Dillard baby No. 2! Children are wonderful blessings from God. Having Israel has been such a delight to us that we know a second sweet baby will only continue to add joy to our family. We are thankful to God for this sweet child and we cannot wait to see her or him face-to-face.”

Even before the two exchanged vows, Jill made it clear that she wants to have a large family just like her parents.

“Both of us want as many kids as God will give us and we’ve talked about adoption,” she said. “My parents kept popping them out, so we’ll see how [our] fertility is.”

Jill is not the only Duggar currently playing catchup with their parents! Jessa Duggar is also pregnant — and she’s only one week away from her due date!

On last week’s episode of Jill and Jessa: Counting On, Jessa hinted at the possibility of twins. Despite being 18 weeks pregnant, she didn’t know if she was having multiples because she had not yet had an ultrasound.

During the episode, Jill — who is a midwife — heard two different heart rates, but clarified that it was possible that she was just hearing the same baby’s heart at two different rates.
