These days can give some structure and creative guidance on cold, miserable days. The choices are limitless, but we’ve done: “yes” day (proceed with caution and set some ground rules), pirate day, space day, doggy day, explore different countries (so Italy day, for example), or make it summertime in winter (crank the heat, put umbrellas in your drinks, pack a picnic lunch, and play with Kinetic sand, which you can make by using one part olive oil to four parts flour). Ask your kids for theme day suggestions, too – they can get creative!
