  Carrie Underwood knew that some of her songs would have a new meaning for her as she became a mom. (:29)
“I feel like ‘Mama’s Song’ does. Songs like that will have a whole new meaning for me, you know, but I just kind of feel a little sad ’cause all my songs are about having girls. (laughs) ‘All-American Girl,’ ‘Mama’s Song,’ I say, you know, ‘I’ll only want what’s best for her.’ Like, little boy baby Fisher’s got nothin’! Even ‘Forever Changed,’ which is one of my favorite songs, is definitely like a mother/daughter kind of a song, so, I’m gonna have to get on that.” (laughs)
