my dck range from 12months-4. I bought enough mini shovels for them all to play with. I also got out some of summer shovels and pails and they mix the snow around with that. Thats a real hit. They play in the backyard, go down the slide, play in play house etc. We have colored the snow too with spray bottles and food coloring and the kids loved that especially the little ones! We go outside everyday for bus run so kids are used to it now. Somedays its 15 mins somedays more just depending on everyones mood.
