When my 2-year-old son sees his newborn sister crying, he toddles toward her bassinet, wraps her in a suffocating hug, and presses his drooling lips against her cheek.He's comforting her in his own way, and it's certainly sweet.But is it kind or altruistic?Does my son care, or is he mimicking his parents, playing a game, and selfishly seeking a reward for acting like he's emotionally engaged?
