//if I had a disabled (or even fully able) child who liked dolls, why wouldn't I? //
Well I dont kow jno, thats sort of what I'm asking.
I'm not so sure a disabled child would want it. For instance one of my daughters is profoundly deaf (from birth). Anything related to hearing problems has always been a no-no with her. She doesnt want to be reminded of her disability, and still doesnt so buying a doll with a hearing aid would have resulted in real problems.
Now I'm sure she doesnt represent how all would feel, but I also bet she's not the only one.
Time and Sales figures will tell.
