This is good information about linguistics. I agree that babies and kids need to know sign language early. My parents are hearing and used home signs and gestures since I was 3 years old. When I was 8 years old, my teacher tried to teach me speech by showing me labels. But I could not read. I memorized colors and pictures. My teacher thought I could read. I was raised orally without learning ASL linguistics. I went to Alabama School for the Deaf from 1969 to 1982. I entered when I was 9 years old. I learned few sign language from my hearing teachers. It limited me from learning English, Literature, Health, Science, and Math. I failed tests. My teachers wasted my education. Thank you. Lisa Smith Powell
Yes, this reflects my childhood.
