Maybe they thought they'd scare the crazy hippy out of you. Lots of first time mums get that message, implicitly or explicitly, even when in perfect health.
Sounds to me like hospital is a bad idea for you. I like the sound of that midwife, though.
Call the IM and have a chat. I'm not anywhere near getting pregnant but the thought of going back to hospital gives the me heebies - if I can't have my own midwife I dont' know what I'll do.
