Hi Doc. My sister can't speak nor hear since birth. Dad tried many DOCs n hosp since her childhood. But docs used to say it will get okay as she grows up. She is 31 now. She can hear load sound and can identity words spoken in front of her. But cannot understand words talked widout seeing her. Please advise. Want to do something. Also her growth is retarded as per her age and she do not have hair growth too.
