I had bacterial meningitis when I was 2 that also caused my deafness. And every audiologist or professional out there kept telling my parents not to use sign language with me and all that junk. I'm glad my parents had their own minds and they learned sign language and did everything they could to help me communicate.. signs, gestures, worked with me on my speech, all that. When I had to be tested before I could go into kindergarten I think it was, they "professionals" said NO SIGN LANGUAGE!, that the signs would be giving me the answers... my mom was so furious.
I hate how professionals just do not understand that the deaf culture is ok. Fine if you want to expose the deaf child to the hearing world, but also allow that child to experience the deaf culture too if possible.
