My parents had to go back to work pretty soon after I was born, so my grandmother who lived next door looked after me for a lot of the time.
She was a voracious reader. I was reading fairly fluently by the age of 3 and able to spell out words ( freaked out a man in M&S by pointing to a sign and reading 'shoplifters will be prosecuted'
)
She taught me to read, add up, count to ten in French Spanish and German ( because that's all she knew...). By the time I went to school at 5 I was so ridiculously far ahead of my peers that I immediately got put up three years on account of my reading ability. Which was fine, but at that point my ability outstripped the 8 year olds. But they couldn't reasonably put a 5 year old in with 10 year olds, which is where my level apparently was. I spent the entirety of my primary school years in classes ahead of my peers, effectively waiting for them to 'catch up'.
Socially it was an absolute nightmare. I was a horrid little prig who thought I was above my classmates. It didn't really settle down until I was at Secondary school and everything had levelled out.
I wouldn't say DON'T teach your child to read. But I'd advise caution. The bonus of my experience is that I have a fantastic vocabulary and can read books at a rate of knots. I'm good at languages, poetry and I have a natural interest in etymology. I also have no idea if those things would have developed organically anyway.
Let any natural inclination towards language stand alongside everyday play, reading etc. if the child shows interest then great. If not, don't force it.
