Did this last winter with the same aged kids. The younger 2 went in the wagon and the older ones all walked. I just made sure to take into consideration the length of time it would take to walk with the kids. By the middle of winter I literally had to drag the wagon though the snow if they hadn't plowed. By January there was really no sidewalk across from my house, the city used it to make a snow pile for some reason. I think I tries a sled once or twice but didn't find it much easier, and then I had nothing for the older kids to hold onto (they all held onto the wagon).

Honestly, it was really awful and I termed my two school age daycare kids because I wasn't willing to do it again this year. No matter what I did it wasn't easy with all the kids, and I felt so bad some days taking them out in the freezing cold.

Luckily this year my daughter is in school and the bus stops right in front of our house so I don't have to take anyone outside.
