The other thing I really REALLY can't handle is the number of people who insist that my birth experience will be exactly like theirs. Even if I was aiming for exactly what they had I probably wouldn't get it, and quite frankly we made a lot of decisions to at least attempt to steer most things in a different direction from most people.
I've heard lots of "as soon as you get there they'll strap you to a monitor and not let you get up until the baby is born" and "if you're lucky they'll let you suck on some ice chips, no eating in labor," and other "facts" that just aren't true for the hospital we're using.
I know they're just trying to be helpful, but at 8.5 months pregnant I just want to scream. I've spent months preparing for this. I may not know what to expect from my body, because no one really knows until it happens, but believe it or not I have researched the policies and procedures for my midwife and hospital and talked about them at length with my care providers. Please stop insisting otherwise.
I think it is so hard for people in general to avoid projecting their own experiences on to everyone around them and with birth, even more so. It's such a huge, life-altering experience and for each person it's so different. The thing is....no matter how much researching and planning you KNOW you've done, it's almost impossible to help people get where you are unless they arrive "there" by themselves. Sometimes it's easier to just say "thanks for the tip" (or yeah, I've heard some hospitals do that, so we did some research and found one that would support my choice to...XYZ - eat, drink, etc) and not even waste your breath trying to help people get that you're informed about your options for birth. Ultimately the important thing is that you and your SO know you're informed enough to advocate for yourselves...wherever you're giving birth.
