After my left Mastectomy, I had a fellow hospital volunteer give me a pretty baby pillow. It helped buffer the stitches from my left arm while sleeping.
And she gave me a shaker jar of corn starch she had made for me, it didn't have all the perfumes and other irritating chemicals in it that baby powder or other body powders do.
That was in 1999 and I still have that cute little purple flowered pillow. (Violet is my legal, birth name, which very few people know)
