Stinky!

This afternoon as I was changing Gavin's very stinky diaper, I said "Oh Stinky!" about 3 times as I was lifting him to the changing table. As soon as I laid him down he said "Stink Stink!" Maybe I am just imagining him saying this, but I swear I heard it! So of course I kept saying stink and Gavin would imitate the "Ssss" sound. He has also mimicked a few other sounds I have made today...and this is a first!
