But that ultimately, she came out the other side with children she feels incredibly fortunate to have. "I guess you wait for things to stop hurting at some point," she told The Guardian.
"I will always mourn those children, those lives that were a shooting star, a breath of smoke, but I have Jacob, and he is incredible, he is the sweetest little baby. "At the time it was awful, and it still hurts, but it's kind of like, 'OK, I have this.'"
Carrie and Mike live in Nashville
While Carrie is careful to protect her sons' privacy - rarely sharing photos of them on social media - she occasionally posts candid snapshots into her family life.
They live on a sprawling farm in Nashville, and Carrie enjoys nothing more than spending time there when she isn't on the road. Her children stay behind when she tours so that they can maintain a routine and attend school, although the star brings them to some of her shows so that they can watch their mom perform.
