Holding his head up

I can't believe how big he is getting--he's already 7 weeks (and 2 days) old!
He holds his head up pretty well now. He's been able to hold it up for very small amounts of time ever since he was born but it seems each day lately, his neck gets a little bit stronger.
Here's a photo of him holding it up while on his belly. And also a couple of others from the same day.
