Remember that your body (pelvis) was designed to widen (up to 30%) during labor......but that this is physically impossible to do if you are laying flat on your back. You need to be standing, kneeling, squatting, etc... So if your pelvis is not currently wide enough to fit a baby through, then definitely refuse the epidural. If the doctors need to do an emergency c-section, they can give you general anesthesia. Just my 2 cents! Good luck!!
