As expectant mother is one person, with whom everyone, right from the inevitable nosy neighbour to the farthest of relatives have an opinion to share.
One of the most exciting opinion of course, is the sex of the yet-to-be-born. But then, I have never ever heard anyone suggesting to the expectant mother (or her in-laws or her poor husband for that matter) that she might be carrying a baby girl...its always the cliched "I am sure its a boy!!!!", so why bother??
