When I am feeding him, he loves to reach up and play with my face... sticking his fingers in my mouth, grabbing my nose (sometimes UP my nose, which we do try to avoid), stroking my cheeks.
He's a snuggler. When he's tired, he just lays his head on my chest and is content to be held.
He loves his mobile. Santa gave him a great mobile for Christmas that shines lights on the walls and ceilings in the dark. When we put him to bed, he automatically looks at the mobile, waiting for it to be turned on. Frequently when I put him to bed at night, I'll close the door so its nice and dark and turn on the mobile and hold him and we watch the lights together for a minute before I put him down. I wish I could get a picture of his face as he watches them -- he's so fascinated by it, but in the dark, its just impossible.
He can hold his own bottle!

The kids LOVE him. And now he's big enough that I'm not too nervous about letting them play with him. Literally, they could entertain Brendan all day long. They especially love it that he can now go in his jumper chair or his exersauser. New accessories to go with their favorite toy!
He's getting into a schedule of sorts. At the very least, I can count on him taking a solid nap in the morning so I can exercise. We're still working on consistently sleeping through the night, but I expect he'll be able to do it by the time he's 4 or 5.
He can get up on all fours! Usually, as soon as he gets up, his legs shoot out from under him and only succeeds in scooting backwards, but its so cute to see his tiny body doing such amazing feats!

He's a barfing machine. Ok, so I don't love that, but it must be mentioned -- the kid is just a spit up generator! His clothes, my clothes, the carpet, his toys, his sheets, his blankets -- if they're not soaked with barf, they are at least crusted with it!
He holds his bottle straw in his own mouth. I love this little gadget -- it has been such a lifesaver -- I can feed him in the car, while I'm shopping, on frantic Sunday mornings when there just isn't 20 minutes to sit around and feed him a bottle. Its not a perfect method, the bottle frequently falls out of his mouth and has to be put back in, but lately, he has figured out how to hold it in his mouth and how to get it back in on his own. Awesome.

He has such an infectious smile. It takes almost nothing to make him smile -- literally just looking at him brings on a big toothless grin. And when you see an adorable smile like this, you can't help but grin back
