Sledding is my kids favorite thing to do in the winter time. We managed to fit it in once before the snow disappeared. To mimic the thrill inside, we used blankets and a little muscle and the kids took turns taking a ride around the house.
I set out their winter gear and they raced each other to see who could get it all on first. Then they had to strike a lovely pose on the fireplace. And to complete the races, it all had to come off.
