I know several deaf parents that have hearing children. When my wife and I were expecting, there was a very real concern among our mutual relatives that our sons would learn to speak well before they attended school. They did not want them being "delayed" in any way.
It hurt .. a lot. You know, I can't think of a more personal degrading remark than to assume that a disability of the parent would hold a child back. It is hard to explain - but as parents, my wife and I were far more worried that our son would be born healthy - and he was - and so was Jonathan.
we see the "polite" silence from strangers, and some 'alarmed" looks when we are in public and using Sign - people in my neck of the woods have never ever been exposed to a deaf family before. It might be something they see on TV, when they are not watching midget wrestling.
And by a Deaf family, I mean one that uses sign, even though both of our boys are hearing, they will learn to communicate with me and their mother. TJ is a little confused by it, he tries to sign to strangers, thinking everyone can, but he is picking it up that his mother is Deaf. When he wants her attention, he knows he has to go to her and tap her.
