A professor of deaf education and a researcher at the University of Tennessee make their case for why they believe sign language is vital for all deaf babies, regardless of cochlear implant plans
here. Kimberly Wolbers and Leala Holcomb write:

Deaf children of deaf parents, whose first language is sign language, end up having better spoken language skills once they are implanted than deaf children of hearing parents who did not learn sign language.
