Yesterday, Jason had Miles in the Baby Bjorn while we were shopping at REI. He kept leaning his head way back, trying to get Jason to lean him back. He's been doing it again today. He seems to love looking at the world upside down!
He has also developed a fascination of watching his right hand. He'll twist it back and forth and just watch it move. I'm hoping that this will develop into a wave, but that might be a lofty goal for him at this point. =)
