The "Not Painful" midwife is fantastic, going by the births she's been involved in. Really calm, relaxed, encouraging - and unlike most of the others who seem to feel the need to scream "push" none stop at the mothers, she seems to tell them not to push sometimes and to let baby do a lot of the work.
However, having never given birth, I don't actually know if this is the mark of a good midwife or not!
