Eeep! Definitely do one anyway. How the hell is she going to know what position you want to birth in if you come in in transition and can't talk? (Apart from the fact that you'd just do it) How would she know to get a ball, or a stool, or mats, or extra pillows? Or that you don't want pain relief offered? Or, or, or...what if? That is SO unprofessional.

Take it higher. For the sake of another mother who isn't as strong and as smart as you.
