Let me also be clear; I intended absolutely no malice towards you in picking this little fight about your usage of this expression. I like your account and I particularly like the humility (and humour) exhibited in your choice of username. I'm also happy that you are expecting another child and are looking forward to it, and perhaps even excited about it.

But I still think the usage of that phrase is wrong and offensive to the very special role of women, in that only they can bring children into the world, a role that is celebrated in traditional cultures but that is being washed away by language such as you have used here, even when you (still) can't see it.
