Childbirth and pregnancy is a gray area in SFF, where the cliches seem to abound and no one does a bare minimum of research about what birth and child bearing is actually like. Kate Nepveu puts out a much more nicely phrased plea for people using child birth and pregnancy in fiction to think a little, and do a little more research. Not every one screams during child birth (actually, as far as I've heard, very few people do!) and some people don't even get morning sickness, for example!
