My favorite thing Nico does is when he gets into trouble, he thinks it over and then sticks his head in my chest. Im sure its just him being Nico, but I like to think of it as an apology! He also does this slow motion turning of his head. I have a video of him doing it...I just think its too cute. Oh, and his snip...we play a game where I try to touch it and he runs away...but then trots back taunting me with it.
