A couple of days ago, I put on a tape of Lotte from 1½ year ago and my wife and me could not believe the difference.!!!
At that time she had the CI for 7 months and she was doing well, but compared to now... it's just amazing. There she would make sounds. Lots of them, but often not recognisable. Now, she is great at repeating words...
It's good to have your own tests.. Like we have her sing a little song now and then, and catch it on videotape, and compare it with the last time we did it.... and the first time.
This gives a good idea of the progres, and the progres is really there.... it's just difficult to capture it.. Video is GREAT!!
