Ta all,
Scummy, it maybe worth a go, but I have tried soooooo many techniques over the 6 years, I am losing heart.
I tried giving her a pound pocket money (she had to earn it, by simply tidying up her room at the weekend.)... guess what? she hasn't and isn't bothered about that either.
I think she has had too many things/toys thrust on her by people (relatives she doesn't see much, and possibly guilt things from me) that she doesn't really have any one thing that really matters.
So, I am getting more + more tempted to clear out her room and start from scratch... she can get her things back through good behaviour.
She has always been fickle with toys etc (flavour of the week, then cast aside)
BTW, she isn't a demon all the time, some of this could be a reaction to ds (who tends, generally, to do as he is told, and wants to try and 'please' us)
She is the classic case of 'difficult' child, who needs more love/attention than the 'easier' one.... but my god, is it hard sometimes!
