I have four kids and it works with me too. It is a funny thing, to be at a large kids' birthday party and then suddenly your ears can pick out the sound that your child is making amongst all the other noise. It also helps that my kids all sound similar in how they cry, so I think it is partly training (hearing the kid cry over the years) and genetics (my kids all sound similar when they cry). I find the other parents can also distinguish their children. It has never seemed to me to be a mother or father dominant trait. An involved parent trait possibly, but not gender related.
