This might be an UO, but I feel the need to post: I can't stand the term "natural birth"--I feel like it's really politicized term (like pro-choice or pro-life). It just makes it seem like if you got pain meds or had a c-section your birth was unnatural and therefore wrong.
It just rubs me the wrong way, which is why I tend to use the term "med-free."
ETA: Just realized that in the Natural Birth thread I used the term "natural birth." Guess I'm a big old hypocrite.
