A L&D nurse mommy blogger suggested this to me, and I think it's brilliant, although I haven't had a chance to try it out yet. The afterpains I had after Bekah was born were AWFUL. I remember distinctly thinking, "I thought this was supposed to be OVER now!" LOL!
The suggestion: Get some of those heated pads that strap on for your back, and wear them strapped over your front, instead, to help ease the pain from uterine cramps.
