Hi Nicola
You could try to introduce a dreamfeed to see if she'll go through but it sounds as though she's waking from habit rather than hunger and you don't want to add the DF if she's not hungry (that's just making more work for you in the long run).
I'd try settling her without putting her on the breast if you can (check out the PU/PD announcement at the top of this forum). You could also try "wake to sleep" to get her out of this habit - there's information on how to do this in Tracy's new book, or if you put a post about it I'm sure someone will give you some tips (I've never used it so don't know the ins and outs).
HTH
love
