Christy Shake guides her son Calvin Kolster from the school bus to their home in Brunswick, Maine on September 29. 2017. Calvin is thirteen, in the seventh grade, and has severe epilepsy and autism. He is also legally blind. "I have to be forever watchful," she says. "I feel like it's probably like having a baby that's learning how to walk but can't quite walk yet and you can't leave....It's sort of that type of vigilance, but it's thirteen and a half years of that vigilance."
