Are you going to have access to a bath? I used water immersion for #1 and #2 (and #2 resulted in a waterbirth - just loved it!)

It felt a little weird when I initially got in the bath because all the weight was taken off my belly so the ctx felt weird. But by the 2nd ctx I was getting use to it and it was a lovely pain relief.

I had many positions that agreed with me in labour. I needed to change positions to find the relief I was seeking. I would get into a comfortable position, stay there until it didn't work for me any longer, then find another position. So make sure you have a whole bag of tricks to try .Maybe write some positions down and give it to your support person so that they can suggest positions to you if you need ideas.
