dreama,
How do you know that modifying behavior wouldn't work for Zoe for Emma? It worked for me. That proves it has the potential to work for them as well.
Besides, Liz hasn't even addressed this with them, so we don't know either way if it will work.
How do you know she hasn't. Been in touch? It should be right at the bottom of the list. They need more communication big time. they might find comfort in these blindisms that you so much dispise.
I had a good friend at doncaster deaf college. He was born deafblind (although he had useful vision. Enough to use BSL by sight). He also had a great personality and obviously enjoyed life. He was a very happy person. He enjoyed college life anyway. He's on the top of my list of favorite people. It's just very unfortunate that we lost touch. These things happen sometimes.
Anyway he also had blindisms. Didn't bother me at all. I just valued his company. The blindisms were no big deal to me.
