Like father, like son

Max has started to have more awake time lately, so Cam and I get to have some fun playing with him. He doesn't smile or laugh intentionally much yet so it's hard to tell if he enjoys our games, but at least we have fun. Cam is clearly enjoying himself in these shots, but I'm not sure whether Max is liking the attention and having fun as well, or is just mildly amused and refraining from crying while he sees where this is going.

It's like looking in a mirror, but who is mimicking who?
