What age to start teaching toddler colours/numbers etc

[BaffledMum22]

FTM here so openly admit I’m 100% winging this 🤣

What age is it developmentally appropriate to start teaching toddlers certain things such as colours, shapes, letters, numbers etc?

Is it something you consciously do with your toddler eg, setting up colour matching activities or naming shapes? Or do you just bring it into everyday chat eg, ‘the ball is red’?

DH and I don’t have any other children in our extended family and we’re the first of our friend group to have children so we’ve never really spent a huge amount of time around them. I have no idea what level of knowledge (if any!) would be expected by the time DS starts nursery at 3 for example.

The first thing that my son learned to "read" was car manufacturers. He could look at the badge on a car and would know if it was a Toyota or Vauxhall etc

His first colours were the colours of his parents cars followed by the colour of his favourite Hot Wheels.
