learning our colors

Look at me posting twice in one day, but I had to write this down before I forgot it. Adi and I were talking about brother Bay and what toys she planned on sharing with him (so far, one of the dogs is the best she has come up with) But then out of no where she said "Brother Bay is brown". Now, we've been working on our colors, and she is getting pretty good at them, so I know she knows what brown is.  I was amazed at how she could put this concept of his skin being brown together. What did she mean by this? So I thought I'd test her adn asked what color Mommy was, she said "white". WOW. Then I asked what color Adi was, and after thinking really hard and looking at her arm she said...PINK! thats my girl!
