WATER! = natures epidural. I know you mentioned you didn't like the bath, but in labor you just never know what you'll like and what you dont like. So at least make it an option. If you dont want it whilist laboring, then dont use it, but if you do want it, it would be horrible for you not to have it! At least give yourself the option. And a bath is very different from say a shower. I recommend at least having both as an option, if at all possible. I know i could not have done my unmedicated births without water (though i know people have different feelings, thats just mine, and so far ive done it twice). Get yourself one of those shower heads that you can hook up and take off to spray against your lower back and that sort of thing. They are cheap and a God-send. Being in the shower is good too since it puts you in a good position to put the baby in.
If you decide to utilize the bath, try not to get in until you are in active labor (4CM or more). If you get in before then it can slow labor. But showering you can get in anytime since you'll be upright.
I would purchase a heating pad.
get large socks and put tennis balls in them (then you can have someone hold each end and rub it on your back).
I got one of those cheap massage thingys that vibrate.
Rice pack.
comfort food/drink
lots of pillows.
support person that understands the natural process (VERY important)
birth ball.
massage/essential oils.
Have your support person watch youtube videos on counter pressure and hip squeezes
music
DOULA!
i would learn how to utilize the birth ball (again youtube is invaluable
). But i wouldn't worry too much about "learning" how to move and that sort of thing during birth because if you are unmedicated and able to do what you desire, your natural instincts will kick in and you'll do what your body and your baby need you to do.
