Lily, but again that points to poor 'differentiation of phonics;' by his teachers.
DS tauight himself to read fluently before starting Reception. He was very interested in books [partly due to not being allowed out of bed until 7 am despite being a 5am waker] so would pore over and over his favourite books, linking his good auditory memory of the story he had had read to him repeatedly to the actual words on the page.
When he started school, he started at the beginning of Jolly Phonics with everyone else. However, his teacher very quickly spotted that he had worked out the phonic code for decoding. This is a key point - he APPEARED to read by sight, but what he had actually done, which if you think about it must be how those who 'read by sight' pretty much always do if they are to read new words, was to work out his own understanding of the 'common phonic code'.
Phonics for him was therefore differentiated by becoming phonics for encoding - for writing, not reading - as easy in many cases as a quick 'DS, can you write some words that have that sound at the beginning / middle / end ... oh that's interesting, that word does have that sound, but can it sometimes be encoded using a different grapheme?'
As a result, he remained a very keen devourer of all things book related, but also became a good speller. he never acquired the 'phonics is boring' mindset, because his teachers were always very quick to show him how phonics was useful for the next thing he needed to do.
The main way IME any child gets hooked into reading is by being read to, and by seeing the people in their lives reading interesting things. So if school phonics books seem 'boring skills practice' - in the same way times tables might be for Maths - then the best way to encourage reading or more maths is having a wide variety of other books that are read to / with the child, and a variety of 'other things to do with maths' (from mazes to magic squares to Polydron) around the place.
