OK - sorry for being terribly stupid here (and as I have NO dogs OR children I am not on any side), but, when I was a child there were dogs AND children sharing the same space. I can't see that dogs poo has got any more toxic over the years, or that children play in different ways. I am not dismissing the dangers of dog poo, but do wonder why it seems to be so much more an issue now than it was 10, 20 or more years ago.
