I gave birth in a semi reclined position and found it easier to push that way cause I could grab my knees and push against myself kwim? It is hard to say before you go into labour what position you would like to give birth in, because it is really whatever mood you're in at the time and what you feel comfortable with. I have done different things with all three births and you just seem to *know* what you want to do, almost instinctively.

I found my biggest problem with labouring on my knees, it that after a while my knees got really sore and I had to keep moving to give them a rest. I did fine a bean bag somewhat useful to lean on and take some of the pressure off my knees, but when it came time to push, I have always liked to be semi reclined and the bed raised behind me to lean against.

So long as you know what you have available to use when the time comes, you will be able to move form one thing to another, or just use the same thing to help you stay comfortable.
