As it was a lovely day here my 2 DDs and their friends asked if I would take them to the local canal by our house (rural area) with small fishing nets so they could play 'fishing'. They didn't actually catch anything but enjoyed messing about by the canalside for an hour. However, when we came home, my DH was horrified that I'd let them do this as he had "seen on the internet the risks of playing by dirty canal water, and that it can lead to infections which in turn can lead to blindness and other serious health risks".
At the time I said "OMG just let the kids live a little", but all evening I've been worrying about it.
Have I put the kids at risk? What do you think? Haven't children done this kind of thing for centuries?
