Shoot, I'm beginning to suspect a trend among women who, I suspect, are discovering that many men don't want to marry women with children - so they do away with the kids, ala Susan Smith, and the recent reports of the women who "forgot" their babies in the car when it's 90 degrees out.
No woman I know would ever kill her child, after it's born.
I can't even think of someone I ever met to level a charge at like that.
