I know it's short, but it's a headcanon, it's meant to be! You all know the drill, please read and review!
Headcanon #1, Teddy
Although many thought he would be, Teddy was never jealous of James, Albus or Lily. It didn't cross his mind when they were born that he wouldn't be welcome in the Potter household anymore, because throughout his life, Harry and Ginny had made it perfectly clear that he was just as much of a son to them as James or Al. He never envied the Potter children for their parents, because while he wished they were still with him, he wouldn't have swapped his clumsy, cheerful, forgetful mother or his brave, loyal, admirable father for the world.
