Ok, I had to come back here after hearing about this.
For early implantation regarding crucial auditory development (as you said above, Koko), I'd like to know what you think about our now-permabanned member, FJ, who was so vocal for years here on early implantation, yet if you read her blogs of even this week alone, Miss Kat STILL doesn't speak "normally." ("Why do you talk weird" is the exact question she was asked by strangers.) She doesn't use ASL (she was pulled out of her bi-bi program.) She even has a broken processor. How does any of this benefit the daughter, Miss Kat? She's stuck with 2 CIs that she got no choice in making to have, one is broken so she gets no auditory help from that one, she uses no sign for back-up, and she "talks weird" (which comes from lack of auditory development!)
Even I, with HAs, was faring better than that at that point in life.
Let the child decide when he/she is of age to decide. Thank you, Naisho, for your post about later-in-life implantation -- that was excellent.
