I never planned to teach my DD to read. She always loved books, and we went to the library when she was about 6 months onwards. She loved looking at books, listening to the story, pointing out the things in the pictures etc, so we spent a lot of time reading stories! I also bought alphabet jigsaws etc. but only so that she would get used to the shapes of the letters and which way up they went. I certainly never named the letters.
Then one day we were in the supermarket, and she pointed to a capital B, and said, "Look Mummy, that's like my name!" She was two! I told her it was a B and we looked for some more. Then I showed her an M for mummy, and we looked for some of those. In the following few weeks she asked about all the letters, and wanted to learn how to draw them, so we did that. She started to read very early, and still loves reading. She is a complete bookworm, but that is just the way she is, it's not because I taught her to read early.
My second DD had no interest in reading. She loved books and stories, but then ran off to play. She learned to read in school, and is now just as good a reader as her older sister. I think children will learn to read when they are ready, the same as other things I suppose, like toilet training. I was a bit of a lazy parent, and did things with them when they showed signs of being interested.
I wouldn't push it. Read lots of stories, sing the alphabet song, play I spy etc. but don't try to teach her letters unless she asks.
