I have read that our great great grandmothers and such never had much problems with posterior babes because they spent alot of time on hands and knees in the garden, scrubbing floors, etc... that this is a problem of recent generations.
I will be inflating mt birth ball soon, and when I am watching a movie or something like that I will chill out on my knees, kinda draped over the ball, with some pillows, etc, to help me get comfy like that. For now I am just trying to make sure I am sitting more on the edge of my seat and not crossing my legs at all.
It's definately worth trying a change in position if you have a posterior (spine to spine) babe.
