Several people have been after me to get a video of Cameron doing his Sheldon laugh. Tonight we were in the bathroom looking at our reflections, and he started doing it. So, I grabbed my phone! This one doesn't sound exactly like Sheldon, but it's a variation of the Sheldon laugh. You can also hear him cough at the end. The other day he discovered coughing for fun, and now he will just sit there and cough and cough and cough. At first I was worried about it, but then I realized he was smiling and getting excited after he does it, and after checking his mouth and listening to his breathing, I realized he does it just because it is a noise.

So here you go! Enjoy my strange little child! Oh! And his first laugh is around 4 seconds. It's that really weird noise he makes.
