I think they ask that stuff if they are also screening for ADHD, autism, developmental delays, auditory processing... For us the red flags are: an uncle with cystic fibrosis, a deaf grandfather and dd spending her first week of life in the NICU after a homebirth. Granted, my father lost his hearing in military service and my dh is not a carrier for CF. Clearly my DYS is brain damaged. (Eye roll.)
