Elusive Thumb

Jackson has been trying to find his thumb for weeks now. He can't quite seem to get it done though. He keeps it tucked into the plam of his hand, so all he can find to suck on are his fingers......which he varies sucking on. Sometimes its two fingers, sometimes its three. Maybe it depends on his mood? Here he opted for three of them. I've never seen him sucking his pinky though. Pinky hater.
