This is my current favorite series of photos of Xander. I wanted to capture his T-shirt, which says "So far, this is the oldest I've ever been," but when I propped him up on the glider, he was being so cute, I didn't care that you couldn't read the shirt.
You can see he has discovered his hands, and is even sucking his thumb a little bit. I didn't expect that to start at 3 months. Somehow I thought babies were born thumb-suckers or not. He's obviously proving me wrong, which, I'm sure, he'll do a lot in his lifetime.
