2-1/2 Year Comparison... the two brown-eyed boys

Ethan and Cooper have been little carbon copies of each other since the day they were born.  I haven't done this in awhile, so figured I would put another comparison up here at the age of 2-1/2.  
 
They have their own looks, but are still definitely very similar.  

 

 

 Can you tell which "sleeping beauty" is which??
