Porcelain dolls, baby dolls, plastic things with vacant eyes that stare at nothing—little girls always get at least one. It's not because they all want to play mommy. Most of them think those dolls are creepy, too.
They're training tools for when the girls grow up and have children of their own. For when they look down into the bassinet and see their baby's smile has grown forced, the laughter turned into a rattle, their eyes too intelligent and cold. They recognize what it is and kill it quick.
It doesn't happen often, but it happens. And when they have a daughter that makes it to childhood, they make sure she has a baby doll of her own.
