Stare, often, at your children while they sleep. There is a certain bond revealed in those moments -- a bond that has been cultivated over thousands of years of evolution. It is not unlike that awe inspiring moment when humans stare into a pristine night sky, far from the obstruction of civilization's glow, and gaze upon the infinite expanse of the heavens. Those silent visual embraces with your children push you back and envelope you all at once.
And they remind you not to kill them when they're awake.
