My Baby is so Big!

My baby is almost two and it is hard for me to swallow.  Most of the time is a sweet little dude who likes to hold my hand and give me "big hugs," and read books with me.  Other times he is naughty and looks at me with a face that says, "I don't give a shit if you told me not to do this, I am doing it anyway."  And then I almost start laughing because his facial expressions are so classic but I don't, because then he would probably end up a serial killer.  Or something.
