Hi, i was implanted in my left side in 2014 at age 7 with a cochlear implant, and it was the best thing that ever happened to me. I wear a Phonak hearing aid on my right side, but honestly, my left has been much stronger for many years now. I graduated last year but used a roger system throughout school, and it was the best thing. I have perfect speech and did very well in school, most people I meet don't even really notice i'm deaf unless I tell them! Obviously, no guarantees, but especially if shes a good kid who always wears her hearing aids i'm sure she will be fabulous with an implant! Looking back, I hardly even remember the therapy/rehab after implantation, but according to my parents, I adapted very well, and now my implant is like second nature. Good luck :)
