Preparing for the SATs?

During a diaper change this morning, Dexter pointed to his socks and said, "Ga". I said, "socks". He kept pointing and saying , "Ga," which was an indication that I didn't guess his attempted communication correctly. I said, "Well, I don't know what you mean, Dexter." He then pointed to the carpet and said, "Ga." I know that he knows the carpet is gray so I said, "Oh, you're saying your socks are gray?" That seemed to do the trick. Dexter smiled as if I had finally gotten the point he was trying to make. Then I said, "Well, Dexter, your socks aren't really gray, they are beige. Beige is to brown what gray is to black." He looked at me quizzically.
