I'm no expert, phonics always seemed to make sense to me, as far as observing my own children and grandchildren.
The English language is illogical at times hence, knife, know etc. However, when my older child went into the infants, briefly there was a head who appeared to endorse the "surround them with books and they'll just pick up reading through word recognition" he didn't subscribe to the phonic approach. Because I found that theory alarming, possibly it works in some instances, I bought a series of phonic books called "Bangers and Mash" my son was reading with the aid of those before 5, my children loved this series as did our grandchildren who also liked to read them to us. Soon after my son went into reception we had a change of head who did a complete about turn from her predecessor and she made it quite clear she absolutely disagreed with his approach and phonics were implemented right away. Much to the relief of the majority of parents.
