Worried about reading? Uh, no... why do you ask?

Cyan was getting me Logan's clothes yesterday and she pulled out a blue striped pair of pants... she says "Look mama! This one has dark blue, light blue, teal, and aquamarine stripes on it!" Alex says "That is more of a green than an aquamarine" she replies "Yes, but aquamarine IS blue and green silly! It's like when you mix teal and green together. And periwinkle is when you mix teal and blue together... see?" I just sat there with my mouth open. She can only recognize 20 out of 24 letters on sight in the alphabet, but for some strange reason I am not worried. ;)
