Faire Jour,
You know you have experienced a lot in life and you know life is full of decisions. By not making a choice, that in itself is a choice. You took all the information available to you and made a choice. The best one you knew how to make at the time.
Having experienced the life altering CI surgery myself, both my wife and I without hesitation would make the same decision for either of our daughters if they loose their hearing while they are under our roof.
Although your daughter may have turned to locate the loud noise "your clapping" prior to the surgery, you can hope that after she learns to use the CI, she will be able to answer your questions without having to turn and look.
Learning to use the CI will probably be a fairly long road for your family and your daughter because of her age but if she comes around like so many other youngsters have on this site, you may say you would do it again in a heart beat.
Do keep us all posted as to her progress.
I didn't see the activation date in this posting. Is it coming soon?
