Notice that I didnt say not to ask for medical advice, or not to take it, I said not to adhere to medical advice that you receive on this website ALONE. As in, do not only use this one source in making decisions. I have surely asked for medical advice, and I call my doctor as well. And I go to other websites, look at studies, and talk to other people in my life (like a midwife, a doula, a LC, and other moms that I know IRL.) My point is that if you are unsure as to why this forum needs to exist if doctors are so great, then I just want to be clear that I think only an idiot would ONLY take the advice given here without getting advice from other sources (doctors included).
And as far as "why are there places like MDC".....umm...because a lot of MDC is about parenting issues, not medical issues. And come on, what momma wouldnt rather hear advice from 30 moms who have had a similar experience than from a doctor that may or may not have ever breastfed or had kids. Theres a forum for almost everything in the world now days, that doesnt mean that professionals are bad or wrong. It means that people like to talk to their peer group about issues that they are having. And let's face it, people on MDC are not always right. No one should be adhering medical advice from this website alone.
It seems like the thread is really asking "why do people follow medical authorities BLINDLY?" not just "why do people follow medical authorities?"
