At birth, Rebecca Carley’s first-born son, James (pictured below at nine months), was a healthy baby with a round head covered with light brown hair.As time went by, she noticed that he always slept with his head to the left side and when awake, often tracked objects with his eyes rather than turning to look at them.After a couple of months, she was startled to see that he had developed a flat spot on his head.Although James’s pediatrician recommended physical therapy for his neck muscles, she expressed little concern about the flattening of his head. But she suggested a possible evaluation at Children’s Hospital Boston.
