I asked my OB last week about whether or not the hospital has birthing balls to use. She said yes, but advised that we bring our own if we have one (which I do). She said that although they clean them after each use, she personally wouldn't trust a plastic ball that other people's ladybits had been laboring on for hours, no matter how "clean". I hadn't really thought of that before. I am not a huge germaphobe, but once she said that, I couldn't get the image of nasty used birthing balls out of my head. Just thought I'd put that out there.
