alien head 

A baby's head isn't hard until at least a few months after birth.

It's soft to keep form killing the mother when being born, but this compresses the head into an elongated form kinda like Kiff from Futurama, but in a fucking human!!!!!!
Its truly one of the most horrifying things you can see as the baby's mother.
