Every woman's dilation speed is different. Some women don't even dilate enough for natural birth so they have to undergo c sect. But we can try to make it easier for our bodies to dilate faster by relaxing more, getting up to walk around slowly or sitting upright , listen to music. I think the moving around or changing position helps although for some of us it will be impossible to walk around with iv drip, epidural and inducing drip stick on us.
I Guess being active during preg helps I was admitted at 8cm without realising I have dilated n was ready for pushing just 1 hr after that ....But I was very active even to the day just b4 my delivery.
