Perhaps you could petition the courts for guardianship of Potterverse due to flagrant abuse of characters? It would be a *really* good thing...
Just like this short story of yours!

I thoroughly enjoyed it, and I was glad to see it was set when the kids were babies. Dunno why, but one of my favorite things to read is Harry & Hermione as young parents. Monitor melting love scenes are another favorite.
I'm telling you... for a short story, this has everything a reader could want!
And I can't believe you got this out with all your other writing. You either write very fast or had some extra time off during the holidays. Whatever the case, thank you for a great read!
