The hole in the mother's pelvis has to be 4 inches (10 cm) in diameter or the baby's head is too big to come out. Shoulder dystocia is an indication that the hole in the mother's pelvis is too small. I am too small to have a vaginal delivery because I have a normal pelvis, but I'm just a small person. I had my one child by C-section which was planned because my doctor was smart enough to figure this out before I went into labor. In the old days I would have died without question. I had no dilation and no dropping. My kid was eight pounds, which I thought was huge.
Some midwives think that all babies can be rotated so they will come out vaginally, but that is not true. My kid was jammed in a diagonal lie. Some people do not believe me. It's not how tall you are or how much you weigh--it's how wide your pelvis is and the size of the hole.
Obesity relates to this as far as gestational diabetes making the baby larger than normal. A certain percentage of women have to have a C-section or they will die due to the size of the baby. I was one of them.
