I love this picture because he looks 99% adorable, but with a dash of crazy/creepy mixed in. Something in his eyes makes me nervous, but I want to chew on him anyway. (also, he still has traces of the impressive black eye he received when he crawled into the corner of my laptop.)
Andy made what he calls the "Ghetto Daddy Rattle." Calvin loves the scrunching sound empty water bottles make, so Andy took one and added misc. pretzels and cheerios so that it rattles when you shake it. The boy loves it.
