Believe it or not, but this woman is 8cm dialated in active labor. She is singing through contractions.
I don’t have nearly as lovely a voice as she does (alas, I was gifted in other areas), but I will have to try singing during labor to help relax me. I sing in my car when I am stressed, so I think it would apply to labor. (And, everything will be hanging out for the world to view anyway, so why worry about how my voice sounds???)
And I sing to my baby in the shower as it is. Maybe he or she will recognize the songs I sing and it will calm both of us?
