I don't have before or after care but have had to take my own children to and from school. Rain or shine I had to be there with my daycare kids in tow. The kids were protected with guards from the weather and snuggled up but I was soaked, cold and it's hard pulling or pushing through snow.
It was nice to get out every day regardless of the weather and otherwise I might have been a bit more lazy to get the kids out on a snow day. We were out ~ rain or shine Great way to get some extra money for sure
I currently have a full crew and it's too much for me personally due to rain and show but many providers do it with rain jacket and snow boots!!
