Carrie Underwood’s intuition is right on.

She only wants her baby to listen to the good stuff during her last weeks of pregnancy. And that’s exactly what she should be doing. Because science says that her baby’s ability to hear is well developed by now, as she moves out of her second trimester and into the third.

During a recent interview, Underwood told Now With Ryan Fox she is getting very particular about what music she listens to, now that there are tiny little ears listening with her.

“I find myself wanting to expose him to good music. So if there’s certain things on the radio. I’ll be like, ‘No, no. We can’t listen to that,’” she said. “And I’ll turn it, then I’ll find something incredible that I grew up listening to. I’m like, ‘Let’s teach him this early.’”

She never admits which songs she is turning off, but she does go on to list a few artists she’d like her baby boy to get to know, including Alan Jackson, George Strait, Reba McEntire and Trisha Yearwood.

Her own songs, like "Something in the Water," would certainly meet her standards for good music.

"I think people just enjoy the happiness that comes through," she said of the Grammy-nominated song. "I think people just enjoy having good vibes comin’ at ‘em."

But that doesn't mean her baby boy reacts when she's signing it live. Underwood's theory on that is that while he is pretty active otherwise, when she’s singing, it's too hard for him to move around.

"I don’t really feel that much of kicking while I’m singing because maybe my stomach muscles are probably bouncing him around in there," she laughed.
