World of Nadiah

I remembered Prof Ainsah told the current psychiatric posting's students about how to take history in psychiatry version. And yes, I clearly remember that she told us to ask about the birth order and she said the youngest always get all the attentions, pampered and the spoiled one. Well, I didn't deny it but it make me angry or sort of disagree. It didn't bother me much, really... because I just knew it's not entirely true. And today, while I was browsing the internet, I stumbled across one website about birth order. So, does the theory of Alfred Adler regarding birth order true?
