Carrie Underwood says motherhood 'changed me as a person'

She's still a singer, songwriter and wildly popular country music performer, but according to Carrie Underwood, she's not the woman she used to be — and that's just fine.

In 2015, Underwood gave birth to son Isaiah, and he opened up a whole new world for the superstar.

"I definitely feel like it's changed me as a person," the 33-year-old explained in an interview with Redbook magazine. "I'm happier. I'm in a better mood a lot of the time. He'll be watching cartoons and I'll be watching him. I'm completely in love. I love it when he's sleepy and I get to hold him and smell him. He doesn't know I'm staring at him and being all googly-eyed!"

In short, motherhood has infused her life with a whole new sense of joy. But given her busy schedule — and that of her hockey-playing husband, Nashville Predators captain Mike Fisher — it's also infused her life with another feeling.

"Sometimes I feel guilty that this is my son's life: We live on a bus and we're in a hotel room and sometimes we're in the middle of nowhere and it's not so great," she confessed. "It's not all glamorous."

And while she finds it hard to ask for help, she said, "I'm learning."

"We have a nanny who helps out, especially when we're on the road," Underwood shared. "But I'd feel guilty asking someone to watch him at home while I run to the grocery store."

But she won't let guilt — or that busy lifestyle — hold her back from welcoming even more joy. She and Fisher hope to have another child.

"If my husband were at the beginning of his career, I'm not sure we could handle it," she said. "Since he's kind of nearing the end and won't be traveling so much, we're like, 'We can figure it out for not that long.' You make it work. When I was pregnant, I thought, 'How am I going to go on the road? How am I going to keep doing my job?' I had to just give it to God and stop worrying about it. Sure enough, we figured it out."
