Heads can mold, pelvises stretch, the position of the mother (ie. squatting, lying on back) and the presentation of the baby's head have a lot to do with it, too. So I guess just comparing head sizes is not very representative of hoiw hard or easy a birth will be. Your attitude is the most important factor, I believe.
I completely agree that you have a lot of factors to consider and that a mother knowledge and confidence in their body plays a major part, just consider this one of my factors , I am trying to get all of the knowledge and understanding possible to acheieve my dream VBAC. Thankyou for all of the information you have given .

IWRT the charts.. I wonder if c/s bubs 'skew' the average, seeing as they are born with nice round heads which didn't need to be squished?
Interesting point, I wonder .

berrme - Best of luck with the birth of your DS2, I hope you get the VBAC of your dreams.

blue daisy - Was that you that wrote the thread about understand the pain of childbirth? I read and printed and re-read this thread when I was pg with DD and it gave me the confidence and understanding that I needed and I had no fears or questions that I could birth my DD naturally. Unfortunatly due to medical reasons I had a labour free CS.

I think I have to hunt that thread down and read again.

I also have nice size hips, as people say mother bearing hips, is that a good sign of pelvis size or an old wives tale?
