Riley is an avid car watcher. As soon as he could sit up he'd be happy to just sit in front of a window and watch cars drive past. Luckily (I think?) for us we've always lived on a main road and 'bus' was one of his first words. Hes still happy now to sit and watch and gives a running commentary of everything he sees (car, blue bus, truck, SUV, another truck, 2 bicycles, a taxi, etc) interspersed with periods of silence and intense concentration. When he was younger if he went silent you always knew where he was and what he was doing.
This photo was taken the morning after our first night in our new house. As soon as he realized he could see the road from our bedroom window he parked himself on top of a stack of boxes and stayed there for ages.
