The link to Hirsch's glossary dropped off my previous post. I have copied both the link and the explanation of 'developmentally appropriate' below.

Developmentally appropriate
If a teacher uses this term, he or she is suggesting that a child's innocence needs to be preserved by not exposing the student to early hard work. The child will learn when he is "ready."
This term, according to Hirsch, is "devoid of scientific meaning and lacks scientific authority," especially as millions of kids across the world have been exposed to and benefited from early hard work.
Yet some teachers feel such work is "developmentally inappropriate" for our kids! This has a particularly disastrous effect for disadvantaged children.
Specifically, he says "many advantaged children receive in their homes the early practice and knowledge they need, whereas many disadvantaged children gain these preparatory learnings, if at all, only in school.
The learning processes involved in the unnatural skills of reading, writing, and arithmetic are inherently slow at first, then speed up cumulatively and exponentially. Because of the cumulative character of school learning, educationally delayed children rarely catch up.
When an elementary school declines to teach demanding knowledge and skills at an early age, the school is unwittingly withholding education differentially from different social classes." Students with poor or disadvantaged homes suffer the most, and social injustice is perpetuated.
Mathaxiety,
Please don't misquote me. I never said that teaching reading at 3 was fine. Nor have I ever said that teaching reading should begin at 4.
What I said was that in order to learn to read, a child must have sufficiently developed the ability to hear the seperate sounds that make up words.
This ability starts to develop around 18 months and, in most children, is sufficiently developed to learn to read at around 3 years. I am not aware of any reading scientist who advocates starting formal instruction in reading at 3 years of age.
However, I know many middle class parents who make sure their children can read before starting school and they start formal instruction at home when their children are around 3.
Most countries start formal instruction at 5 which is why I stated that this was the most common age.
Since you are clearly unfamiliar with the evidence-based literature on beginning reading, I suggest the most user-friendly place for you to start is the Children of the Code website.
