(After the excitement of the first few signs wore off, I kinda got lazy. But that's not important right now.)
One of the signs Tesla has in his arsenal is "hat". Kind of a useless one, when compared to "please", "more", "food", or "potty", but hey. He signs "hat" whenever he sees Silas in a beanie, baseball cap, or bandana (which is frequently).
The first time he tried to touch the inside of a 350 degree oven, I exclaimed, "No, Tesla! Do not touch! Hot!"
He looked surprised and a little confused by my reaction, and then reached up to pat his head. "Hat?"
Today, I knew the damage was done when the timer for the oatmeal chocolate chunk cookies went off and he ran excitedly to the oven and stood in front of it, patting his head vigorously. "Hat! Hat! Hat!"
Oh well. Close enough, right?
