mystery, solved.

Marc just answered a question that's been thrown around here for a few days now... What is J looking at? When he's in his car seat in the living room, he's frequently staring up toward the ceiling. Previous theories about what he was looking at included the pictures on the wall (dark frames providing interesting light/dark contrast), the sprinklers on the ceiling (for their resemblance to nipples), and the lamp (reenacting his most vivid memory and attempting to "come into the light").

Turns out he was looking at the handle of the car seat.
