Children's book authors have always known this to be true. A.A. Milne, author of the 'Winnie the Pooh' series, based his stories around his own son, Christopher Robin. Pooh, Tigger, Piglet, Eeyore and others have their origin as the inanimate creatures you see above.
"Oh, papa!" she cried. "There is Emily!"
A flush had risen to her face and there was an expression in her green-gray eyes as if she had just recognized someone she was intimate with and fond of.
"She is actually waiting there for us!" she said. "Let us go in to her."
"Dear me," said Captain Crewe, "I feel as if we ought to have someone to introduce us."
"You must introduce me and I will introduce you," said Sara. "But I knew her the minute I saw her -- so perhaps she knew me, too."
She looked at the staring glass eyes and complacent face, and suddenly a sort of heartbroken rage seized her. She lifted her little savage hand and knocked Emily off the chair, bursting into a passion of sobbing -- Sara who never cried.
"You are nothing but a doll!" she cried. "Nothing but a doll -- doll -- doll! You care for nothing. You are stuffed with sawdust. You never had a heart. Nothing could ever make you feel. You are a doll!"
Emily lay on the floor, with her legs ignominiously doubled up over her head, and a new flat place on the end of her nose; but she was calm, even dignified. Sara hid her face in her arms. The rats in the wall began to fight and bite each other and squeak and scramble. Melchisedec was chastising some of his family.
"You can't help being a doll," she said with a resigned sigh, "any more than Lavinia and Jessie can help not having any sense. We are not all made alike. Perhaps you do your sawdust best." And she kissed her and shook her clothes straight, and put her back upon her chair.
