A baby asleep on your chest

There's something so comforting about having your son fall asleep so completely on your chest. That feeling of weight as he gradually stops squirming and turns into a sack of potatoes. When his head slumps over, turned into your neck, check pressed against your chest, so that he's shaped like a comma. His breathing changing from all the struggling and catchy squawking to a calm in and out, falling in rhythm to your own chest rising and falling. More than anything, I adore that feeling of complete and utter trust that this implies.
