My sons were 4 when they wanted to learn how to read from their older sister (7 at the time). I diverted their attention and learned them how to play chess instead 
(anything that&#x27;s not taught in primary school would do).<p>The reason was this: if they can read before primary school, they will certainly be bored out of their minds, and would be detrimental to their school experience.<p>Today, I still think it was the right thing to do.
