Ya frost bite is a concern in winter for sure specially for those who do not 'move' outside ... my winter policy is if Environment Canada has issued a 'cold weather alert' for my city due to extreme windchill and cold or if it is colder than -10 taking into consideration 'windchill' and conditions in the yard ~ aka they might have a windchill of -15 but the actual temperature is only -8 than I would still go out because my yard has privacy fencing that blocks most wind at least at the 'kiddies' level.
