Miasmummy, my birth experience with ds was very distressing, and I then went on to develop PND. I don't think that the birth was really a major factor in the PND, probably more likely the problems I had with breastfeeding (or maybe it would have happened anyway). But OTOH I had a very good birth experience with my second child, dd, bfd her for nearly 2y, and did not develop PND. So, yes, it can go well the second time, and, what's more, the 'good' labour totally made up for and wiped the slate clean from my 'bad' first labour.
At about 35w pg with dd I had a long debrief with the Liaison Midwife at the hospital were both my children were born. Her job was specifically to discuss women's birth experiences with them, should they choose to do so, whether it was a few hours after they gave birth, or a few years later.
She had all my notes with her, we went through the whole business in detail - not just her reading the notes and explaining, but me talking about my labour and my memories of it. It was an excellent experience, not overly distressing for me at all. She was not judgemental, not critical of my anger, but accepted my feelings.
One of my issues was with a particular midwife, and the Liaison M/w literally gave me permission to tell that m/w - or anyone else that I felt uncomfortable with - to go away and not come anywhere near me. This would not jeopardise my care. In the event, when I was in labour I did tell the senior midwife that I didn't want X to come anywhere near me, and that was the last I saw of X.
So I would say, approach this meeting with the consultant with a positive attitude, and if you are not happy with either the way he treats you, or with the outcome, bypass him and talk to the midwives. Many hospitals have this sort of service, only it's often poorly publicised (if at all).
