Robin, I was actually beginning to worry about Nate and his colors too. I've been trying to teach him shapes and colors for awhile and he doesn't seem to be getting his colors at all. He will randomly say "blue" or "red", but I can tell he isn't getting it at all. I've actually started researching if Nate was color blind as well, and some of the articles I've read that it's a hard concept for them to grasp. I know it's so hard not to compare because my friend's daughter who is a week older than Nate started saying her colors at the age of 16 months. Now, she is literally saying complete sentences such as "My shoes don't have laces." Nate's barely putting two word phrases together. Alright, I think I got completely sidetracked, but I don't think you should worry about Lela being colorblind. If you're still concerned, I think you should take her to the pediatrician to be safe.
