My older brother had Guillan Barre years ago. I wont go into details. He married a woman who also had it at young age with no permanent effects from it (they shared tracheotomy scars though)...
I have known a number of other people who have had mild cases of Guillan Barre with no permanent damage and made full come back from the paralysis, especially when stricken while young. I hope your daughter does well, you are there with her and supporting her, she should do good!
Take care of yourself also during this time - it wont help your daughter if you let yourself get worn out while she is going through this. (It happened to my mother during my brothers illness)
