Hi Claire
My daughter is 6 months old, my birth plan included things like;
what sort of pain relief I was open to using
What positions I would like to try, birth pool etc
My views on epidural, forceps etc
Whether I wanted vitamin k injection for baby/ injection to speed up delivery of placenta
My health board gave us a questionnaire in ante-natal classes to fill in. For the most part I just let things happen as and when but if there is anything you feel strongly about (I didn't want forceps) put it in and make sure your birth partner knows your views as you might be too out of it at the time!
Hope this helps, good luck for the birth (no where near as bad as I expected)
