Question: Why do they not refer to Pooh as Winnie? His name is Winnie the Pooh.
Answer: "Pooh" is his name of endearment. If you think about the people in your life, maybe the people you went to school with, you might remember several who were referred to most often by their middle name or their last name, or some nickname or designation other than their first name.
Answer: In the original book, near the beginning when talking about Winnie it says "his arms were so stiff... they stayed up straight in the air for more than a week, and whenever a fly came and settled on his nose he had to blow it off. And I think-but I am not sure-that that is why he is always called Pooh."
