They're captured in this 'playing' session.
Yeah, playing is one of Aidan's jobs nowadays. I'm sure we adult are jealous of him, I'm included.
When he's not smiling, often he still gives us his shocking look.
This is actually another famous look of Aidan, as some of you may know.
He still can't sit for too long on his own, so most of the time his playing time is monitored by mommy.
He's more interested in things that moves, so playing the ball will be a good fit.
He's still easily distracted though, by my flash, for example.

But he'll soon be back to his business. And he must be very eager to play, judging by his drooling. =P
And it turns out he's more interested in chewing mommy's palm.
FYI, this disgusted-like look is not related to his chewing of mommy's palm. =P
