Cool Dude

Ty has really started to become a little man this last week. He has suddenly had a fondness for hats and wearing them backwards. This Saturday after getting him dressed he says "Mommy my hat". So I get him his hat. I tried to put it on him, but as always he can do it. He puts it on the right way first and I say..."oh, how cute"..He immediately gives me this "Uggggh" and turns it around...Then he looks at me again and says, "Cool Dude" with his thumbs up. Where do they learn these things?
