she's 7yo now. we were told she wouldn't talk and would be unlikely to walk, but has always been a determined type. although the pattern of her brain damage (from birth hypoxia) means her whole body is involved, she's made brilliant developmental strides. she used a walking frame until 5, but now she walks, talks, shouts, runs, goes to dance classes, brownies, and loves to ski.
and she's very bright, which is a bit tricky, because she has dysarthric speech and so gets patronised a bit. mostly she's independent now, but still needs ot etc (will be a keyboard user rather than writing long term).
i'm still not entirely sure that cp is what you are looking at though, and every kid with cp is differently affected. i'm glad genetics are doing their stuff - it's always a long wait though, i'm afraid. i remember sitting in scbu with another mum wishing we could look into the future and see the kids at 5, thinking that would give us all the answers, but of course, it doesn't. when they are 5, you want to know how they will be at 10, then 15, then adult. sn is a tricky game. 
hope you get on well at skinuk - they are a great bunch of people - i've been to some of their meet-ups and it's amazing to see the kids changing and developing, as well as spend time in a completely non-judgemental environment.
