I found this interesting article describing the author's feelings about controlling pregnant women, birthing plans, homebirth, and birth experience here.
The authors describes "birthzillas" as women for whom it's all about the birth experience and not the baby. Or, as someone else describes it, throwing the baby out with the water, so to speak.
The authors goes on:
"At the extreme end of the Birthzilla spectrum are those women who put their birth experience above the health and wellbeing of their baby. And yes it happens. In fact the South Australian coronor recently found that three babies who died during homebirths would have certainly survived had they been born in hospitals. In each case, their mothers knew the pregnancies were high risk and chose to give birth at home without medical support anyway. Their babies died. And for what? That is where Birthzilla behaviour can actually be a matter of life and death. "
