Don't be too sure that the children without hats and with open coats took the items off on the bus. The twins (3 1/2) were the only children at their preschool in snowpants and boots. While nobody was in a dress, several children didn't have have on mittens. What killed me was that some of these parents were looking at me like I was nuts for over dressing my kids.
Oh, and so far the preschool is open tommorow. I would keep them home, but I have to take my DD out for an appointment with a pediatric orthapedist (DS will come too). It took two months to get this appointment, so I don't want to cancel. Since we'll be bundled up and out anyway, I'll probably bring them to school.
