What was doodle's appearance as a baby in the scarlet ibis?

In James Hurst's short story "The Scarlet Ibis," Doodle is described as a frail and delicate baby with physical disabilities. He has a "tiny" body and is so weak that he initially cannot even sit up or crawl. His large, bright eyes and a small, pointed head give him a striking appearance, making him seem almost bird-like. Despite his fragile condition, there is a sense of beauty and innocence about him that endears him to his family.
