You did not ask for pity, so I will not give you that. I just hope that you
and your family will come out of this stronger as a family after this
difficult time.
Also, I would maybe suggest these two games:
http://games.kde.org/game.php?game=ktuberling
http://edu.kde.org/klettres/
Both are available in Trisquel add software.
I am not sure, however, if this was what you were looking for or not...
Please, try to explain in greater detail what you need, I am not sure if
these games will be of any help or not (at least it will allow her to listen
to words, maybe you can use that to help her repeating them).
I would also sugest making not only a search for "kid's software" but
"english learning software" in general. People who want to learn a new
language often use that kind of things. The games I posted have more appeal
to a kid, but maybe more adult programs would be helpful too.
Keep asking more questions, will try to help with this.
