It's freezing out. Gone are the days of running out of the house without the big, bulky winter coat, hat and mittens.

I found some helpful information and guidelines on this consumer report. It explains how you can determine if your child's coat is too big for the car seat. It also includes a couple of suggestions for keeping them warm in the car.
