that thing where they smear cereal/food in their eyebrows or hair
that thing where they are so sleepy, and lay their head on your shoulder
that thing where they look at you and you can tell they are trying to say something, but they can't speak yet, and all that comes out is "nananananananana...nana?"
thumb sucking (it's still gross to me, but whatevs...it's pretty stinkin' adorable)
the look they give you when you give them a new food...like "seriously, with this?"
