Joel had sleep apnea for the first two years of his life and was then diagnosed as autistic, has ADHD and a speech and language impediment/sensory disorder, and Caddie helps him to cope with a life that he finds incredibly hard. Caddie is Joel’s friend, helps him to communicate with people, calms him in times of heightened stress and grounds him by resting on his thigh, lets people know Joel has a hidden disability, finds Joel if he flees, gives Joel confidence and sits next to him to keep him at the table. Caddie opened up a whole new world to Joel and to their whole family.
