Thanks for all the replies.
I am actually in communication with a 3rd year student midwife that I was put in contact with through an agency called midwives naturally. I have been speaking with her about my pregnancy and she has also attended a couple of my antenatal appointments. It is also up to me whether I want her to be present during the birth and she has offered to support me and act as a sort of advocate for me.
Part of me thinks it would be a good idea to have her there with me (as well as my husband, and possible my mum too) but another part of me only wants the people with me that really HAVE to be with me. I don't want to feel crowded when I am having this baby but I am also scared that I will be too wrapped up in what I am doing to question any decisions by the docs etc that I may not be happy with.

I definitely understand that things don't always go the way we want during labour - my last labour was a good example of that - but I want to at least have a go at doing things the way I want before having any kind of interventions that I hadn't anticipated. The epidural is something I will definitely consider a lot earlier this time if the baby is posterior but up until I am in too much pain I would like to labour the way I want, nothing to 'tie me down', no constant monitoring, I want to be able to get in the bath or shower whenever I want etc. I just get the feeling that with the glucose drip and the anitbiotics I have already been told will need mean that I am going to be more restricted and probably require more monitoring than I was hoping for.
I guess I am just stressing about things that may not even happen but after my last experience I am really hoping for less restriction when I'm in labour and also no stitches, I would really be happy if I could get out of it this time without an episiotomy!
