Empathy...

I'm wondering if there is a study out there that states that multiples develop empathy earlier than singletons. 

Even though Mary Catherine and Henry are only 19 months they can be so sweet and considerate of each other.  The times I notice it the most is in regards to food.  They often share food and carry sippy cups to each other.  It melts my heart. 

However, this sweetness is only reserved for each other.  Other siblings do not receive this sharing of food and toys, but rather shrieks and shrills that can break glass miles away. 

Today, the empathy reached a new level.  Henry was put into time-out because when I told him I was going to change his diaper he flipped his lid.  So, I put him in time-out, in the usual spot, and Mary Catherine went and sat down beside him.  It was so cute that I just let it go.  Of course, it backfired on me because then Henry didn't want to get up and was content to sit there as long as she did.  It wasn't until I got her up and put her in her bed that he gave me a hug (which signifies 'sorry') and got up to get his diaper changed without hysteria.
