My mom and brother are hard of hearing.
Decades ago, the local school system offered SEE classes to family members of students that were receiving services.
Years later, I used baby signs with my children.
Now I want to learn ASL. Honestly for the first time since SEE and "baby sign" are not ASL. Sure, there are crossover signs, but that only gets one so far.
I also have occasional aphasia, so I'm hoping that learning ASL will do two things 1)offer me a resource when I get stuck and 2) help me recall when I get stuck.
