I agree with the suggestions here not to push phonics, but I want to suggest two things that you might want to have around in case they take your DD's fancy:
- first,
http://www.starfall.com , which my DS loved around the same age. (The ABCs section was a favourite for a long time; he used other sections too, but not so much.)
- second, if you have the budget (I say this because DS went through them like a house on fire and buying a new level every week or two gets pricey!), some of the Oxford Reading Tree Songbird Phonics readers. I chose these for DS-then-2 because he was clearly learning phonically to some extent (to my surprise - he was obsessed with spelling at 2.5!) but I think they'd work for a whole-word learner too in fact. I decided to get reading books for him because he was getting frustrated with story books which would have a few words he could decode/recognise followed by one he couldn't. We had a rule that nobody ever read the reading books *to* him, they were just for him to read. We'd tell him a word if he had trouble with it, but actually it seldom happened: they are very carefully graded. We never explicitly encouraged reading - there was no need to! - but we did have a rule that at bed time he got two stories read to him, and then could go on reading to himself as long as he liked, so reading was the only acceptable bedtime postponement ruse.
