This is a case for common sense. I went out yesterday....I have only preschoolers no wee ones.....the wind was gusty in Ottawa not dangerous. If the sky looks like a storm is coming or wind is too high we go in... In winter though in Ottawa we go out up until -20 including windchill og course ( we would never go out if temps were lower) of course if you have younger ones you shorten your time outside.... Sometimes I find we have too many policies and not enough common sense! Why didn't the daycare staff go inside ? Is my question ........
