On the Ontological Quandraries of Baby Photos

Just got back from a family reunion out at Long Beach (Washington, that is), and for one of the activities my Dad constructed a poster board with baby photos of everyone in the room and we had to guess whose was whose. For the life of me I couldn't match a single one to anybody's, including my own baby photo. The people who did guess right were mostly just remembering baby photos they'd already seen. When did we become adults? And how do we make it stop?
