I think it is a bit weird that the word 'gender' has replaced 'sex' on everything from application forms to surveys to online forums. If someone asks about my baby's 'gender' I could say I don't know what their sexual identity will be, but that I could tell them the sex because that is a biological fact. Are we really becoming so prudish that we can't bear to use the word 'sex'? Or do people just not know the difference anymore?
