(CNN) — Matthew Allen’s 10 brothers and sisters have grown up helping their parents take care of him.
Ranging in age from 2 to 27, they are his playmates, his protectors, his teachers and his advocates.
They taught him to talk, but they speak for him when he doesn’t have the words.
And they all dread the possible phone call bearing the news that something awful has happened to him.
Matt’s a middle child; he’s 16, and he has autism.
