— -- As Carrie Underwood settles into motherhood, there's one thing that comes naturally to the country star –- singing lullabies to her baby boy, Isaiah.
"I sing all the time, I didn't even realize... He's just exposed to me singing all the time," Underwood, 32, told ABC's Robin Roberts in an interview for the ABC News special, "Countdown to the CMA Awards: Country's Greatest Crossover Hits with Robin Roberts."
Underwood and her husband, professional hockey player Mike Fisher, welcomed their son in February, and the new mom might be able to get some parenting tips this week from Brad Paisley. The two country stars will team up for the eighth time to co-host the 2015 CMA Awards on Nov. 4 on ABC.
Paisley has two sons, Huck, 8, and Jasper, 6, with his wife, actress Kimberly Williams-Paisley, and he told Roberts he has been singing to his kids since birth.
"'You Are My Sunshine' is the first song I sang to my children when they were born," Paisley told ABC News. "I took actually a little parlor guitar to the hospital."
Paisley said it was his wife's idea to sing to the boys when they were born.
"She said, 'Wouldn't it be neat if one of the first things they hear is you playing the guitar and singing?'" he said. "So that's what we sang.
"It's interesting," Paisley continued, "Because they know the song and they got to the point where they heard the lyrics and they realized it sounds like such a positive song."
