You are making an assumption
I haven't said whether I am exposing my son to ASL yet or not, so you may be assuming that we are not. My son is not yet 6 months old, but we have been signing simple signs to him.
On a technical note, I disagree with your analogy simply because a CI does not amplify sound at all. I do agree with you that he will always be deaf, and I appreciate that thought. Too many times have I read comments that he'll be a "vampire" or "cyborg" and neither deaf nor hearing.
I don't feel that I am depriving my son of language development at all. We are using signs to this point, and he'll likely get his implants within the next 4 months.
