“It’s going to be a different ball game, for sure,” she told the outlet. “My brain, I’m such a planner. I want to know how it’s all going to go. But no matter who you are, you make it happen, you make it work, you get your team behind you.”

Back in April, the American Idol season 4 winner dished to PEOPLE about striking thebalance between work and familylife, saying the couple’s “whole life has changed” since welcoming Isaiah.

“I remember when we first found out we were gonna have him it [was] like, ‘How are we gonna do this? Our lives are so crazy as it is,’ ” said Underwood at the time.

“But you just make room and you learn how important that family time is, and to be able to spend time and carve out some of that and maybe get to go on vacation and maybe get to go on a cruise — that stuff is so important to, like I said, make time for family,” she added. “That’s what it’s all about.”
