Great wording for the birth plan, Kelly. I wrote one very similar, but as someone else said, it was more so that I had it in my head. I think I was a bit stoic about the way I wanted things to go, so I was really disappointed that things didn't go according to plan (Charlie was posterior and I ended up having an epidural). I reckon the most important thing is to have someone being an advocate for you - as long as they know your preferences and any specific requirements you might have then they can be your spokesperson. Ideally this should be someone that is strong enough to 'stand up' to the midwife if he/she turns out to be less than what you wanted and ignores your wishes. For example, I was SO against having pethidine, and DH was really good at not giving in to the midwife when she wanted me to have it instead of an epidural. Because he was able to 'fight' for me (I can't think of a better way of wording it, but you know what I mean) I was able to get what I wanted and needed.

Sorry, I babbled on a bit, but I hope I was helpful!
