I'm probably being over-anxious here...
My DS seems unable to learn or recognise colours. He's only 2.4 yo, but he's so clever in other ways, e.g. can count to 20, forwards and backwards (!), he can do 30 piece jigsaws without help. So is it realistic of me to think he should be able to learn colours now? I've tried playing games with him, pointing out colours in books, colouring in etc. Our child minder has tried teaching him too, she has made this term's special topic colours, they've done collages and made posters, but he's unable to say what colour things are, and he's pretty much always gets it wrong if he makes a guess.
Does anyone out there have a colour blind DC? At what age did you realise?
