How far is the walk? Usually there is busing available for jk's unless less then .6 km away from school. I'm sure if it's not too far then it should be manageable as the bad weather doesn't usually start until dec and is gone by march .... Having said that I don't do school age unless they go to my kids school as the bus comes right to my door. Maybe just do a bit earlier lunch have a nice walk over and usually there is supervision in the school yard 15 mins before school so that would get you back home a bit earlier and get the kids in bed and maybe suggest the parent find a older student to walk back to your house and you can take $5/day off her fees .... But I know how you feel cause I have four two yr olds too and an 11 month old ... Good luck
