When my son Rowan was 8 years old, he was diagnosed as autistic, something that should have been obvious given his aversion to hand-dryers and his proclivity for completing puzzles face-down. The doctor cautioned that Rowan would need more time to process things in school, but I soon realized that my son not only thought but moved on a different pattern of time, one that was slower and frequently at odds with the norms of modern childhood.

In Rowan’s early years, I’d yet to hear of “crip time,” a term used by disability activists and scholars to describe their uneasy relationship to various modes of modern life. In her book “Feminist, Queer, Crip,” Alison Kafer explains that crip time recognizes that “expectations of ‘how long things take’ are based on very particular minds and bodies.” Not surprisingly, those “very particular minds” seldom include the timelines of autistic people like my son.
