DS was 2 in May. Around May he started getting a note home from school once a week saying what they did that week. The one week it was they they worked on the color green, that was the only color week they had. He's been home with me all summer. We go over colors often, and everything is green to him. I thought it was kind of funny, like this is the only color he learned at daycare, but now I'm starting to wonder if he's color blind. I casually point out colors often, but he doens't seem to be picking it up. Yesterday my dad was doing blocks with him and asking him for different colors. It seems as though my son has no idea what a color is. When I asked him to give my dad the triangle block he seemed to understand a bit more clearly what a triangle was than what a color was.
Any idea how you determine if a child that young is color blind? I thought he may need glasses because he often squints at the tv, but his vision was fine at his 2 year old check up. The dr. did ask me if he knew his colors, I said no and he just said to keep working on it.
