The fourth-season American Idol winner and mom of son Isaiah Michael, 14 months, toldPeople backstage at the 2016 American Country Countdown Awards whether she'd be up for having more children with husband Mike Fisher.
"Oh definitely!" Underwood, 33, noted.
"I'm not sure when because we're both kind of busy these days. But yeah, definitely. And I'm like, '[Isaiah] is so good -- I could do a few more of those.'"
The "Church Bells" singer explained how Isaiah is a "good guy" and an "easy baby."
Underwood and Fisher, a 35-year-old pro hockey player for the Nashville Predators, got married in Georgia in July 2010 following their December 2009 engagement. The couple had dated for about a year before Fisher proposed. The singer and Fisher later welcomed their first child in February of last year.
Underwood also provided some details on what it's been like to be a mom. For starters, Isaiah isn't being raised on Underwood's strict vegetarian diet.
"He loves everything. He's not a huge meat eater, but he likes turkey and stuff like that. Lots of veggies," the country singer told People before rattling off her son's interests.
"He likes to sing. If you just go 'la-la-la,' he'll go 'la-la-la-la.' He mimics really well... He's into everything. He runs. He babbles. He's a good eater."
Underwood, however, must have to watch Isaiah like a hawk.
"Right now he is a climber, which is not good," Underwood shared.
Underwood just walked away with the award for Best Female Vocalist Sunday night at the ACC Awards in Inglewood, CA.
