I need slow contemporary country songs. Please help?

I am a preschool teacher and I am in desperate need of some slow music for naptime. I usually listen to rock, but I do (secretly lol) enjoy some country. I really like Rascal Flatts, Carrie Underwood and Taylor Swift. Anyone else yall can think of to help me out? PS: If anyone asks, it's "for the kids"! Haha (;
