I'm pretty sure he's throwing a baby gang sign here...
See how his thumb and fingers form an A, as in Awake? He's a member of the "No Sleep" gang.
It's a relatively recent development. After a rocky start, he was only waking up once or twice for a couple of months. However, this last week it's back to 5 times (or more) a night. Someone please tell me that this is a growth spurt, and that it will end shortly.
"Pink blankets? I eat pink blankets for LUNCH! Nom nom nom nom nom!"
Oh, and he hasn't pooped in three days... I'm sure you all wanted to know that...
