The mother does not know what a deaf person needs. They do not know the ramifications of partial hearing loss on their educational and social lives. They do not know that CIs and hearing aids do not solve everything. Parents are not being properly informed by the medical community. All of that has to change. How can a mother do the right thing when she doesn't even know what that is because of partial information? How can a mother know that deafness is a way of life, not a crippling disability when the first time that comes out of professionals' mouths upon "diagnosis" of hearing loss is "I'm sorry, your child failed."
That's ominous and implies that without extreme intervention, a deaf child is doomed. How can a parent not be influenced by this when making their decisions?
And I firmly believe that when a child asks for CIs, they are already having the mindset that they are prepared to do the work to get maximum benefits from their CIs and I have heard very good success stories of kids who got implanted at age 8,9,10,11 and upwards and had managed to keep up with those who were implanted shortly after birth.
