I'm sure they are helpful, but are they really so necessary? I'm planning on doing things naturally and have a few books that teach techniques, and the hospital I am going to doesnt offer natural birth classes like some of the other sutter hospitals do in my area, and I dont know if I would want to take childbirth classes at a different hospital than I will be delivering at. I am for sure taking a breastfeeding class though... When I said this to her she looked like she was about to poop her pants. Necessary?
