There are certain things that we need at the very beginning of our lives that give us a fighting chance for the world.  Regular touch releases serotonin in the growing brain.  Eye contact creates synapses for proper social attachment.  Hearing an adult's heartbeat steadies our own.  We know our caregivers by their scent before we know them by sight.

When you hold a baby that small and that fragile, and to see them smile up at you or fall asleep in your arms, there is still somehow all the hope in the world embodied right there that great things will happen.  Life is too important.  At the beginning, there's a choice for us to begin anew and make things better.  By God's grace, each one of us is known by Him as a child for our entire existence.
