My 4-year-old autistic son injured his fingers twice within the same month at his ABA therapy center when his fingers got caught in a bathroom door, despite being under 1:1 supervision. After the second incident, we discovered he had fractures in two fingers. A few days later, one finger developed a serious infection with pus, requiring an ER visit and surgery under sedation at a children's hospital. A plastic surgeon had to remove his fingernail and clean the infected area. We were told the nail could take up to a year to regrow.

I'm concerned about how this happened twice at the same center despite being he getting good therapy there. Has anyone experienced something similar? What would you do as a parent? Should I consider legal action for cause of medical bill and suffering?
