I would have to agree with Chas, 12 weeks is nowhere near long enough to start thinking about what may or may not be possible, friend of mines daughter is in a wheelchair & has limited upper body & hand movement she has never given up on being able to walk, lost count of the number of painful operations she must have had. She was 18 before she managed to stand for the first time ever unaided by others. She is 23 now & still not given up on the idea of one day being able to walk.
