I see kids dressed like that all the time.

I'm sure I did it, too, when I was that age.

My son NEVER wears a coat, unless I force him to - even then sometimes I know he takes if off and carries it. And, we live in Wyoming, it is below zero much of the time, and he has to ride the bus.

What can you do? Eventually their brains will expand to catch up with their bodies .... we hope.
