Awwwn! He looks super cute positioned like that.
Speaking of kids and imitating trust me they are super good at it. It's not good to do something bad in front of them cause they would really put it to practice. My sister's daughter imitates her father a lot too especially when it comes to how he talks to someone on the phone. Whenever he's home, he would lay on the couch cross his legs while speaking over the phone. One day my little niece got hold of her dad's phone went straight to the same couch, lay on it, crossed her legs and pretended to speak with someone. I was astonished and couldn't help but laugh.
