Kelly Im not trying to knock you or others who are Doula's, I do get that till I have had one I wont fully understand.

But it sounds to me that people are expected to just accpet that there is a rift between midwifes & doula's so the doula is only going to tell you how to rock the boat & not do it for you. I may be totally off the mark but from all of the things I have read here on BB & on websites that Doula's have promoting their services I was under the impression that this was part of the service the couple is paying for.
The labouring couple should be able to get on with giving birth while the Doula is the voice of reason. I realise that one would need to be tactful in their approach and being the voice to say to the couple, lets take a moment to discuss this in private is great. But what happens when neither are in the right frame of mind to do this. This is where I thought the Doula steps in and says This is what is on the birth plan, this is what was discussed prior to labour, this is what my client wants/doesn't want in this situation.
