Of course this is easier when there isn't anyone around, somehow.
However, after five months of this, I've now become so accustomed to it that I don't hesitate anymore to quickly whip off Umi's nappy in public parks, friends' gardens, and any other green space, and let her relieve herself. Baby wee (and even, usually, baby poo) is so innocuous - I can't imagine anyone being offended. However I suppose there ought to be some kind of social protocol around it; asking if it's OK to E-C while there are people standing around. Any ideas?
