If a woman has a small frame does that mean that she will be tighter down there and have trouble in birth?

Of course not, I have seen small women have big babies and large women have c-sections.
not true...
The vaginal orafice stretches during childbirth. The size of her pelvic bones is a greater concern- although the pubic symphasis does give some.
no not at all
Usually not, babies are special ordered to fit mommies womb.
No. I have a very petite cousin who has 5 children, none of whom were born in a hospital because once she goes into labor, the babies are born so quickly she has never ever made it to the hospital.
Not really.
I have had fat girlfriends that were super tight and skinny girlfriends that you felt like you were going to fall in.
That is why the test drive is so important.
