I am a reader; I'm not interested in fiction particularly but I read absolutely extensively, constantly and on more or less any topic, so the internet always appealed to me.

My siblings, also non-fiction readers, both learned to read before they went to school.

I point-blank refused: I was confident I could learn to read, and with the now-long-lost confidence of a summer child, at the age of less than four, I said "no, that is what school is for".

When I got there, I was reading well above my level within the first couple of weeks.

I assume that as well as my parents showing what reading was, I had seen my brother reading, and he had read to me and had shown me what learning to read looked like.

The point of this disjointed anecdote is: be engaged, be inquisitive, show yourself learning and exploring; if you are shown a puzzle, approach it as if you don't know it. Furrow your brow comically, make mock mistakes, show your working. Enlist others to play these learning game.

You don't have to worry about teaching your son anything except that learning is great, and if possible that all sorts of adults have all sorts of things they can teach.

Once your kid is at school, then you can fill in the gaps; then you can be the extra teacher who engages with the subject matter (which as an adult you will have long forgotten and really can approach with fresh eyes).

It's your job to help make a learner, not to be a teacher.
