Isaac Milestone -- Social Interaction

Tonight when I got home from work, Isaac did something that he has never done before, and he did it first with me. He locked eyes with me, and he smiled. He did it many times. All of a sudden, my little lump of baby flesh has actually become a little person with an inner life. I even have witnesses.

Man, this freakin' rocks. Parent crack! Parent crack! Parent crack! You see it, and you're hooked and you push the button until it breaks. Pretty soon he got tired, but after he rested up again, I tried it again, and it worked -- he smiled at me. I swear, this makes all the sleepless nights so completely worth it.
