Maybe this is a naive question...but I was wondering.
People say to expecting parents, it'll decide when it's ready to be born... but does it?
Is there something in the baby itself that cues the birth process, or is it the woman's bady that says, "enough of THIS".
If you think about a chicken in the egg, the SHELL doesn't say "crack me now". It's somrthing in the chick that says it's time to start cracking.
So what about human (and mammal) births? The female body, or the baby?
