My children have been years ahead of their agemates linguistically, but emotionally and developmentally they are right on track.
I'm glad for you children - that's a wonderful circumstance. I don't think that is the case for most gifted kids. What I see more of are children who have a wider range of behavior than most - sometimes they are acting their age, sometimes younger than their age, sometimes years older. If we judge them by their most immature behavior, then sure, they can look 'right on track' but that oversimplifies their internal reality.
I've seen children playing happily with stuffed animals, and they may even be increasing their social skills through practice, but I wouldn't be comfortable if that was the full picture of my child's social interactions. And, perhaps more importantly, no authority figure acts like that is supposed to be the full picture of a child's social interactions.
