Oh dear. This ole chestnut again! I know some parents can be incredibly gross about this kind of thing, and it can be offensive, but don't be too hard on them. My daughter was very difficult to potty train indeed, and sometimes if they need to go, they need to go. Better in the drain than soaking their clothes and filling their shoes and then having to, say, get on a bus to go home freezing cold and soaking wet? I know it's grim, but sometimes it just does happen.
