Haven't read the whole thread but people who are anti phonics are just as unhelpful as people who are anti learning sight words. You need both to read.
You need phonics and later, spelling/pronunciation rules like 'tion' to decode previous unknown words, but you also need to sightread common non-phonetic words which cannot be decoded.
To the person who complained about 'the' being a tricky word, well it is tricky because the e doesn't make its phonic sound, as in the middle of bed. It's one of the first sight words they learn in Reception along with I, he and she. Tricky just means not phonetic.
To the OP, if no-on has mentioned them yet, Usborne Very First Readers are good as they have a few words for the child to read and some more on the opposite page for the parent to read so the story is more interesting.
Also ignore people who tell you not to teach your 4 year old to read. If she's interested then go for it. Mine could read fluently before she started school and basically learned with very little assistance from me. She has never ever complained of being bored at school. However, reading to her and maintaining a love of stories is at least as, if not more important than teaching phonics or sightwords.
