hub2dee - I haven't read properly the later posts on this thread, but you ask what you can do to help your dp have a good birth. IME three things are important:
1 Delay going to the hospital as long as possible to ensure that things really are moving before you submit yourselves to the medical establishment.
2 A confident, informed attitude from both of you. You especially are the advocate and need to keep your wits alert. With my first birthing, once I had had the epidural, the midwife wanted to put in a syntocinon (?) drip to speed things up, and we refused. We wanted her to at least examine me first to decide whether it was warranted. We had to fight very hard for that, and when she finally agreed to do that she wanted to break my waters at the same time. Again, a very hard fight on our part. Eventually, when she did examine me, dh went and stood nearer the 'action' end to make sure she didn't surreptitiously use the little hook.
Which leads me on to point 3: A midwife that you feel good with. Whenever my midwife couldn't 'manage' me she went and got the senior midwifery sister to deal with me, and that's how we met god's gift to womankind - the best midwife in the world. When I was in her hands I trusted her, I obeyed her instructions and she got me through to a safe delivery. With my second birthing I fortunately arrived on the labour ward while the same sister was on duty, and asked for only her to take care of us. I specifically asked for the other one (who was also on duty) not to come anywhere near me. It was the best decision - once again I felt I trusted her, wanted her near me and obeyed her, and this time had an even better birth. It's your job as the advocate to ensure that your dp feels comfortable with her midwife, and if the working relationship is not good, then you can ask for a different midwife.
In UCH, the attitude is generally very good towards patients. But of course there may be indivicuals with whom you do not 'click'. Certainly my good experiences at UCH vastly outnumber my poor ones, and I had care in different parts of UCH during my pregnancies.
One aspect that I found poor though, was that if during labour you don't seem to need help then, beyond checking up on you, they don't spend much time with you. That was a lesson we learned from my first birthing, when we were left alone for long periods because we seemed to be managing OK. 2nd time around we made fusses! And got the attention we needed.
