Before I forget, Benjamin is smiling. Has been for almost a week now. He doesn't do it regularly, but I do believe it's definitely a social smile versus just some random facial twitch because when he does it he is looking at me and it's generally in response to something silly I'm saying to him.

Oh, and he is batting at his hanging toy that hangs over his playpen. Donald has this on video. While it does seem awfully early for this, it's happened too often to just be an accident.
