DS1 is 2.5. He's pretty good at colours but am noticing more and more that he almost never gets 'red' right and instead will say 'don't know' or 'green'.
How early can you tell if a toddler is colour blind? Is there a suitable test he could take? And, if he is colour blind, are there any tips for dealing with it?
I'm inclined to think it's not a major issue - unless anyone wants to enlighen me with things to worry about??
(There's no colour blindness that I know of in the family.)
