I *love* male lactation stories! Not in a kinky way, though kinky is fine with me, but just in a way that combats the notion that nurturing is a feminine-only phenomenon, and that gives all those nurturing feelings someplace to go. This, plus Sherlock overflowing with caregiver sentiments, is a beautiful thought. And John can't nurture Rosie as much as she needs, since he's still grappling with all that grief and anger. What a good use for Sherlock's remorse.
