Twin babies have telepathic connections

I had a family recently give birth to identical twin babies.  I put them in cribs next to each other before they had even learned the speak and yet I noticed positive interaction symbols above the cribs and the babies were actually interacting with each other.  No one else was even in the room at the time.  I find it useful because they never got lonely just "talking" with each other while the parents were busy doing other things.  i have heard of real world twins being able to communicate with their own made up languages no one else can understand.
