As we waited in an Expo queue ahead of us was a child perched on his father's shoulders. Nothing remarkable there, except for the big gap in his pants revealing an unclothed bum. Yesterday in a metro station we saw parents holding their child over a rubbish bin as urine streamed out of the gap in her pants. Both front and back are open. They don't seem to use nappies here. How they know when their child is about to void their bladder or bowels or get them somewhere suitable in time, I don't know. I've heard that toilet training is far easier though. Not for Alex, sorry.
