Excellent information. My daughter immediately comes to mind. She was born at 29 weeks gestation. Spent her first three months in NICU and PICU. She cried for the first year of her life. We did not know how to soothe her. My wife cried. we did not know if she was hungry, in pain or what. At eleven months old she was diagnosed with Cerebral Palsy. She is intelligent but she must rely on a wheelchair and limited hand use. She displayed many of the traits you describe in this article.
