get a sled! We had my old one, but it didn't have a back, so M couldn't sit up when I pulled her (perhaps b/c her snowsuit is kind of terrible and bulky). I ordered one with a back from Amazon, and it is so much fun! We went to the park by our house, and the snow was so deep, she could drag her feet through it when she was swinging on the baby swing. But man, I am tired!
