I have kaiser so I have to choose between Good Sams or St Joes for birth. I am very much focused on having a natural, unmedicated birth and have been reading up on it. I know from the research I've been doing that most natural birth advocates do not recommend hospital-run classes for natural mammas. Has anyone done the childbirth classes at these hospitals? I'm trying to decide if they would be a good choice or if a DVD/natural childbirth class would be a better use of our time.
