Jinger Duggar, Jeremy Vuolo Waited to Tell Daughters About Baby No. 3 for Fear Felicity, 6, Would Spill the Beans (Exclusive)

Jinger Duggar and Jeremy Vuolo had good reason not to tell their eldest daughter that they’re expecting another baby.

The couple exclusively announced to PEOPLE that they were expecting baby No. 3, revealing that Jinger, 30, is due in March 2025. The Counting On alums are already parents to daughters Felicity, 6, and Evangeline, 3.

While the TLC stars planned to tell Felicity and Evangeline the big news before they announced it to the world, they also held off on sharing it with the girls right away.

“Part of that is because we have a 6-year-old who is a total extra extrovert and will be walking by a stranger and tell them the news,” Jinger explained. “And so we thought, you know what? We’re going to tell the girls pretty soon, but we’re going to wait until closer to the time that we announced to tell them.”

“But we [were] waiting because she’s in school and she would tell every single person. That’s just how she is,” the 19 Kids and Counting star added.

Jinger added that their daughters had different reactions to the news. While Felicity “started jumping up and down in excitement,” Evangeline “wasn’t quite sure what to make of the news” — though Jinger is sure that once the baby arrives, “[Evangeline] will be all about her new role as big sis.”

While the couple knew they wanted a third child, Jeremy admitted he was “speechless” when Jinger told him she was pregnant again.

Jinger told PEOPLE that she surprised her husband with the news on Felicity’s 6th birthday, presenting him with a “gift” from Amazon — that was actually her positive pregnancy test.

“Yes, it was something we were expecting,” Jeremy recalled, “but I was still shocked.”

When asked how she is currently spending her time, Jinger said she is just trying to “cherish” every moment with Felicity and Evangeline before their new addition arrives.

“They’re so excited [about the new baby], but I think it’s also change. I’m just enjoying these moments with them.”

While the reality TV stars do not yet know whether they are having a boy or a girl, Jinger shared they will be “happy either way!”
