I have a 6 years old son with PDD- Autism. I and wife are hard of hearing. We have two children a daughter 8 years old not autism. Our son entered early intervention at 2 and hald years old. We as family used total communications voices, American Sign language, pictures and expose to social outing with friends and family.
Since our son is able to repeat words back with command with the American sign Language and his PACE book demonstrating communication needs.
He social very well with sister and friends who he sees often.
It would be a great tool for the Autism Community to include American Sign Language as non verbal to communicate with family with autism child which will reduce frustration with family.
