My oldest son, who was a good early reader, became that way despite everything. Age 5/6/7 he had a very poor attention span at school, was exceptionally distractable, didn't listen to the teacher and at the end of year 1 was put on the school's SEN register for his behaviour in class. He was also diagnosed with hearing problems which he had all through primary school.
The school he was at gave out the odd work sheet (about 4 a term) and a book a week. This was six years ago, when literacy targets for teachers seemed less rigid.
I can't say dh or I did much literacy work with ds at home, or even got him to read through the books he was given. We read to him most nights (10 minutes at the most) and chatted to him generally about words he queried, but nothing much else. We were relaxed about his reading progress because he was picking up reading easily and his teachers had no worries about his ability. Our attention was fixed on his behaviour issues. I can't even tell you what methods he learned to read by - he definitely did not have the ORT books or Jolly Phonics.
He really was one of those children who just picked up reading for himself. I think he would have got there by whatever method he was taught. He was not a hugely advanced reader, but learning the basics was never a problem and, once his behaviour calmed down, he was in the top reading and spelling sets from Year 4 onwards.
I have put in far more effort trying to teach my youngest son to read at home. He gets a literacy worksheet from school every week, spellings to learn and ORT books to read. Like his brother, he is also not a good listener to the teacher. Apart from this, we have far fewer behaviour issues with ds2 at school. His hearing is perfedt. By rights, he should have been the better reader, but to coin two cliches 'life is not fair' and 'all children are different'.
