Euphemia, Yes the whole class has the tricky words, we have also had Stage one words, 12 words- I, the, to, he, me, is, his, put, was, want, saw, no. We were struggling with those tbh and then they sent home the 18 stage 2 words. She has managed to 'learn' some of the Stage 1 words. Having read all of your replies I realise that I should have been delighted that she managed some of these instead of trying to get her to cram the other 18 words as well.
She has been sent home with The new Trainers, The Bad Dog, the new dog and others I can't remember
I think this is where the Everyone comes into play, 'Everyone wanted a new dog' etc. She at least as an understanding of the meaning of the word, when asked what word she replies ' all of them?' 
Really, thanks everyone for the replies, I feel much better about it all at least although the issue remains that DD is finding it all quite overwhelming I think. We do have a stage 1 Songbirds book Cornflake that she had been looking at with me and quite enjoying as she has a good sense of humour and the first couple made her laugh but she is not interested just now. Will go back to it when her enthusiasm picks up again.
