A partner is someone to help you. This can be your husband, your doula a friend - or a combination. Having someone physically near you is comforting in labor. It also doesn't hurt to let someone else remember which position works well with what situation.
Slow dancing is a great position for labor. It can be used in any stage of labor from early labor all the way up through transition and pushing. Slow dancing has the added benefit of using gravity. Gravity will help your baby descend into the birth canal, which can speed your labor. Being able to dance or sway with music or without can also aid in relaxation.
Your partner can rub your back while in this position. Or they can simply hold you up. You could also have someone else, like your doula, rub your back while you focus on your husband.
