Where did that come from?

I have no idea where he got it from, but Colby started to fake cough this weekend. He just started to cough and then look at me and smile. I kept asking him... where did that come from? I think he thinks it is funny that he can make a new sound. Whenever someone does it back to him, he repeats it again. He gets so proud of himself. It is the cutest little thing.
Eating is going great! I don't think he is going to be a picky eater like his mommy and daddy. He already eats more fruits and vegetables than me. He got his first taste of fruit on Sunday, and of course loved it. He now eats: peas, carrots, green beans, sweet peas, squash, sweet potatoes, and pears.

Here is a video of the FAKE cough!
