It is not a good idea to replace your regular sitting furniture with a “birthing” ball, even if the birthing ball is more comfortable while you’re sitting. (And by “replace” I don’t mean I tossed all of my furniture out onto the street and I’m only sitting on this giant, inflated thing. I mean “instead of” regular furniture.) Its job is to widen your hips in the hopes of making delivery easier. What the books and the videos don’t tell you is that sitting on the ball ALL the time will also make it very difficult to walk. Very.
So, ladies and gents, as with all good things–everything in moderation.
