The girls are about to be outnumbered in Josh and Anna Duggar’s house!

The reality stars of TLC’s 19 Kids & Counting, who recently announced their third baby is due in June, tell PEOPLE they are having a baby boy.

Along with the rest of the Duggar family, they decided to find out the baby’s sex, and filmed the announcement for their show, which airs Tuesdays at 9 p.m. ET).

“We didn’t know the results,” Josh, 25, tells PEOPLE. “But we gave them [from the doctor] to the sound guy, Jim, and he planned out this very unique reveal. It caught us off guard in a time and place we least expected.”

Already parents to daughter Mackynzie, 3, and son Michael, 21 months, Josh and Anna say that, like Josh’s parents Jim Bob and Michelle, they are open to having as many children as “God gives us.” Still, every pregnancy is exciting and every child a new gift, he says.

“Oh yeah, we have this all figured out,” says Josh, with a laugh. “No. The most seasoned parents will confess their inadequacy. Each child is so unique and so different. It is just amazing.”

Anna, 25, says that she wants to focus on enjoying each of her children.

“I am so thankful for our children,” she tells PEOPLE. “It is not about having a bunch of babies. It is about enjoying each child God has given you and focus on every day that you get with your child.”
