Honestly, I think it would be more fun if it'd be a boy. How Klaus would train him, expect him to become more like him... How the boy would try his hardest to get his father's approval. I think it'd be more fun. I'm not sure how Klaus would be around a daughter... I want him to be a father who expects much from his child. And with a son, it seems easier to do. A girl would probably get along with Hayley more.
