Had to throw my $.02 in!! (sorry!)
-It is great if you can stay home as long as possible. Only go to the hospital when you start to feel like you can't cope anymore (or, as in my case, when your hot water runs out LOL)
-Believe in yourself. I think this is a BIG one. You can do it and you need to believe that and you need your DH or support person to believe it too.
-Remember that transition can be the time when you feel like you just can't cope anymore - but that means that you're nearly ready to push so just try and work through that difficult bit.
-Labour in an upright-ish position. Gravity will speed your labour up.
-Listen to your body first - before anyone else. The medical staff will treat you like your labour is going to progress in a typical way but it might not and only YOU know what your body is telling you. (eg. my midwife thought I wouldn't make it without drugs when I showed up at hospital 3cms dilated. She told me I had HOURS to go. I was fully dilated and pushing just 1 hour later)
-Find a relaxation or breathing technique that works for you. There's heaps out there and I found it really confusing to read so many different techniques. I think it is best to pick a couple that suit you and focus on those.
-But most of all, be open minded. It is great if your labour goes according to plan, but it might not. Be prepared to change your plan if necessary and remember you will have your baby to cuddle at the end regardless.

Good luck!
