Pip82 I had my last two with CMWA. My midwives were fantastic, I haven't met Emma though I hear she is a lovely and very capable young midwife. I would have to say though that my experience of the actual 'program' was better the first time as they have changed quite a lot in the time between dd2 and ds2 (less than two years!). And I can't honestly say that I would use them again as it has become really quite 'systemized' for want of a better word, and not really how I (or my midwives) feel homebirth should be!
but I really hope that your experience is a happy and enjoyable one and you don't feel too pressured to do anything you don't want.
