Surely you have lots of cardboard boxes arriving to your doorstep with all that online shopping you’ve been doing! Instead of immediately recycling, use them to help your little one make a snowy mountain scape. Cut the cardboard into two triangles of equal size. Cut a slit up halfway from the bottom on one and halfway down from the top on the other. Paint the top (or decorate with stickers or washi tape or anything else you can attach there), and slide the bottom slit into the top slit. Create several, and use dollhouse figurines to make-believe winter in the mountains.
