N.B.
I don't have a good answer for you. My daughter is 16 now and all thru her bussing years, I bugged at her to wear warmer shoes and gloves and such! We are in MN.
Now, as a home daycare provider, who is home and sees the other ages of kids walk past my house at 3 time intervals each weekday, on their way home from the bus each afternoon....the high schoolers first, then middle school then last the elementary age kids. And I am shocked and amazed to see NO ONE is wearing a coat. They almost always are carrying their coats! Even this week when it was like 15* with a windchill making it feel even colder! It baffles me!
It is to be snowing about "go home" time today....wonder if any of them will have their coats on, or just over their arms like I always see....geeze!
Good Luck!
