No, you don't get a raise, because you didn't ask for it. The difference you should be focusing on, in your scenario, is not that I had a kid. It's that, for whatever reason, I renegotiated my salary. If you can do the same, then you get the same results.
See, whereas you never quite understood the "what if you have a kid" argument, I never quite understood the "don't I deserve the same as that other guy" argument. The way I see it, the magical answer is always the same: maybe you do. Do something about it and you might be surprised.
