I thought that the nurse that brought me a flavored Popsicle was God. I fell in love with her, I think.
It was also nice for them to help me breathe through my contractions and to help keep me calm. I was convinced I was dying, so it was kind of nice to hear that my body was doing exactly what it was supposed to.
Ice chips for her mouth and lips, maybe brushing her hair away from her face or lightly fanning her face, whispering encouragement, watching the contraction monitors for her and letting her know when they're coming and when they're going away, etc.
