Subject: What are the expected qualities of children in a family (i.e. oldest)?

I have often heard if there are two 
children in a family, the youngest is 
supposed to be very social and the oldest 
ought to be very smart.  With three 
siblings, the oldest should be very 
organized, and so on.  Well, I am 
interested in the cold hard facts.  I tried 
internet searches and the information 
must be out there, but I don't know the 
correct keywords.  Please refer me 
somewhere or give me the scoop.  What 
is expected from certain children and 
siblings in a family?  What are the 
qualities they possess and lack?  Please 
let me know ASAP.  Thanks a bunch!
