I think that books and cartoons are a great way to teach kids English. Try to find her favorite cartoons but the DVD so you can put them in English. Many cartoons are originally in English to begin with.
I have recently written an article on how kids learn English and you can read it here Kids learn English by Playing, so how can you get them to play in English?
Also you can play games with her. Like happy families, guess who etc.
Have fun and she will learn a lot.
Best of luck!
