We sign at home! It is her primary language, so it is the language of communication in our house.
And I am not looking for this to happen overnight, she was HOH for 3 years, amplified "well" with speech services from this school, with literally ZERO progress. We started seeing a private AVT and she made stunning progress in a very short period of time. I keep being told "Language is the key. If you sign, speech will come later." And we did exactly what "they" told us. So here we are 4+ years later, and she hasn't made the progress. We put her in an AVT enviroment for 3 hours a week and she is suddenly taking off. We are now starting to question what we should be doing to help her best succeed in all areas.
