I'm curious, in my region (greater Seattle area) almost all the hospitals have birthing centers that are attached to the hospital, but aren't "the hospital." They are nicely appointed rooms with birthing beds, baths, exercise balls, bars etc. They have hidden doors that can "transform" the room in to a hospital room at a moments notice, and if needed the NICU is down the hall. We needed the NICU once, so I was glad for the option. Is this not commonplace in the larger hospital markets (where I would assume most HN'ers live)?
